What is a bankroll in sports betting?
The total amount of money a bettor sets aside for wagering
The commission charged by the bookmaker on each bet
A type of multiple bet combining several wagers
The predicted probability of an event occurring
A bankroll is the total sum of money a bettor allocates exclusively for betting purposes. It helps bettors manage funds and avoid overspending.
What do betting odds represent in sports betting?
The implied probability of an event occurring
The predetermined payout regardless of outcome
The fee the bookmaker charges for placing a bet
The total amount of bets placed on an event
Odds translate the implied probability that an outcome will happen into a numerical ratio. They also determine the potential payout relative to the stake.
What does "vig" (vigorish) refer to in sports betting?
The bookmaker's commission built into odds
The bettor's total potential profit
A type of multi-leg bet combining outcomes
The calculated break-even probability of a bet
The vigorish, or vig, is the margin or commission that bookmakers include in odds to ensure profitability. It raises the implied probability above 100%.
Which of the following is a moneyline bet?
A wager on the outright winner of a single game
A bet on the combined point total of a game
A series of bets combined into one with increasing odds
A wager on the point spread of a game
A moneyline bet is a straightforward wager on which team or individual will win the event outright. No point spread is involved.
What is a flat-betting strategy?
Wagering the same fixed amount on every bet
Increasing bets after each win
Doubling the bet amount after a loss
Adjusting stakes based on confidence level
Flat betting means risking the same unit size on every wager regardless of outcome or confidence. It is a conservative bankroll management approach.
What is the implied probability of an outcome at decimal odds of 4.0?
25%
40%
4%
75%
Implied probability is calculated as 1 divided by the decimal odds. Thus 1/4.0 equals 0.25, or 25%.
What is the decimal equivalent of fractional odds 5/2?
3.5
2.5
7.0
2.05
To convert fractional odds to decimal, divide the numerator by the denominator and add one: (5 ÷ 2) + 1 = 3.5.
What is the expected value (EV) of a $1 bet at decimal odds of 3.0 with a 40% chance to win?
$0.20
$0.80
- $0.20
$1.20
Profit per win is $2 and loss is $1. EV = 0.4×2 + 0.6×(-1) = 0.8−0.6 = $0.20.
Which bet type is generally considered the least risky?
A single (straight) bet
A parlay
A futures bet
A teaser
A single or straight bet involves one outcome and has no dependency on additional legs, making it the least risky compared to multi-leg bets.
According to the Kelly criterion, what fraction of your bankroll should you bet if decimal odds are 3.0 and your probability of winning is 50%?
25%
50%
10%
75%
Kelly fraction = (bp - q) / b, with b = odds −1 = 2, p = 0.5, q = 0.5 gives (2×0.5−0.5)/2 = 0.25 or 25%.
What is "chasing losses" in sports betting?
Increasing stake size after a loss to recover funds
Stopping wagers immediately after a loss
Only betting on heavy favorites
Placing bets on multiple events simultaneously
Chasing losses refers to the strategy of raising bet sizes after a loss, which often leads to greater risk and potential depletion of the bankroll.
Which practice helps avoid emotional betting?
Setting predefined stake and loss limits
Relying on gut feelings
Increasing bets after a big win
Betting on every available event
Establishing stake sizes and loss limits in advance prevents reactive decisions driven by emotion and helps maintain discipline.
Compared to a single wager, a two-leg parlay has:
Lower probability of winning and higher potential payout
Higher probability of winning and lower potential payout
The same probability of winning and higher payout
Lower probability of winning and lower payout
A parlay requires both selections to win, reducing the probability but offering a larger combined payout for the increased risk.
Which factor is commonly considered by oddsmakers when setting odds?
Key player injuries
Individual bettors' personal preferences
Local fan loyalty
Random chance only
Oddsmakers analyze objective factors like injuries, weather, and team form to assess event probabilities before adjusting for vig and public money.
What is an arbitrage opportunity in sports betting?
Simultaneous bets on all outcomes guaranteeing profit
A single bet on the point spread
A combined multiple bet with increased odds
Betting against the bookmaker's favorite
Arbitrage exploits differences in odds across bookmakers by betting every outcome so that a profit is locked in regardless of the result.
Calculate the bookmaker's margin for a two-way market with decimal odds of 1.90 on each side.
5.26%
2.63%
10.00%
0.00%
Margin = (1/1.9 + 1/1.9) − 1 = 1.0526 − 1 = 0.0526, or 5.26%. This represents the bookmaker's built-in profit.
With a $1,000 bankroll, decimal odds of 2.5, and win probability of 45%, what is the Kelly criterion bet size?
$83
$225
$45
$62.50
Kelly fraction = (b⋅p − q)/b with b=1.5, p=0.45, q=0.55 gives ≈0.0833. On a $1,000 bankroll, 0.0833×1000 ≈ $83.
After the 2018 PASPA repeal in the United States, sports betting regulations are:
Determined individually by each state
Uniformly legal across all states
Prohibited under federal law
Allowed only in Nevada
The Supreme Court's decision to repeal PASPA in 2018 allowed each state to legalize and regulate sports betting independently.
Which scenario best illustrates confirmation bias in sports betting?
Focusing only on stats that support your pick while ignoring contrary data
Recording all bets and outcomes impartially
Using a mathematical model to set odds
Randomly selecting events to bet on
Confirmation bias occurs when bettors seek or emphasize information that confirms their preconceptions and ignore evidence to the contrary.
A bettor wins 55% of their bets at decimal odds of 1.91. Are they profitable over the long term?
Yes, because the break-even win rate is about 52.4%
No, they need to win at least 60%
Yes, any win rate over 50% is profitable
No, because odds under 2.0 always lose money
Break-even win rate = 1/1.91 ≈ 52.36%. Winning 55% exceeds this threshold, so the bettor has a positive expected return.

Cheat Sheet

  1. Understand Different Odds Formats - Odds may look like math homework, but mastering decimal, fractional, and moneyline formats is easier than it seems. For example, decimal odds of 2.00 means you win $1 for every $1 you stake, while 3/1 in fractional odds means a $1 bet returns $3 of profit. Practicing conversions helps you compare bets across platforms and never miss a winning opportunity. Investopedia: Betting Odds Explained
  2. Calculate Implied Probability - Turning odds into probabilities is like running a secret background check on your bet. With decimal odds of 3.00, you divide 1 by 3.00 to find a 33.3% implied chance, giving you a clearer view of real risk. This skill lets you judge if the payout justifies the stake every time you play. Investopedia: Implied Probability Basics
  3. Explore the Kelly Criterion for Bankroll Management - Think of the Kelly Criterion as your personal betting coach, telling you exactly how much to stake based on your edge and bankroll. The simple formula f* = (bp - q)/b helps you balance growth ambitions with caution to avoid bankroll blowouts. Use it wisely to increase stakes when you have an advantage and dial back when you don't. Wikipedia: Kelly Criterion
  4. Analyze Point Spread Betting - Point spreads level the playing field by adding imaginary points to the underdog's score or subtracting them from the favorite's. If Team A is a 7-point favorite, they need to win by 8 or more for a bet on them to cash. Understanding this tweak helps you spot when oddsmakers overvalue or undervalue a team. Wikipedia: Spread Betting
  5. Grasp Over/Under (Totals) Betting - Betting over/under is like predicting the total scoreboard fuss without picking a side. If the line is 50 points, you win by staking "over" and cheering for a fireworks show, or take "under" if you love defensive battles. It's a pure bet on excitement level, perfect for fans who enjoy every point. Wikipedia: Over/Under
  6. Recognize Common Betting Pitfalls - Don't let the gambler's fallacy trick you into believing past losses change future outcomes. Beware of overconfidence after a winning streak and emotional bets on your favorite team. Staying objective and disciplined is the ultimate power play for long-term success. Investopedia: Common Pitfalls
  7. Understand Sports Betting Regulations - Laws can be all over the map, so check the rules where you live before placing bets. From age restrictions to taxes, knowing the legal landscape keeps your hobby legit and stress-free. Plus, it's always more fun when you don't have to worry about compliance. Wikipedia: Sports Betting Regulations
  8. Evaluate Different Bet Types and Their Risk Profiles - Single bets are low-risk and low-drama, while parlays offer sky-high payouts if you hit every leg - otherwise, you lose it all. Teasers let you adjust point spreads in your favor, but they come with smaller odds. By comparing these options, you can tailor your strategy to match your thrill level and bankroll. Wikipedia: Bet Types Explained
  9. Apply Bankroll Management Strategies - Flat betting keeps your stake the same, while percentage betting adjusts your wager based on bankroll size, letting you ride hot streaks and weather cold spells. Consistent staking plans protect you from big downswings and help you grow steadily. Treat your bankroll like a team asset you can't afford to lose. Wikipedia: Bankroll Management
  10. Utilize Machine Learning in Sports Betting - Machines love stats, and ML models can crunch historical data faster than any spreadsheet jockey. From player performance to weather conditions, smart algorithms uncover hidden patterns and help you spot value bets before everyone else. Learning these techniques can give you a high-tech edge in the betting arena. arXiv: Machine Learning for Sports Betting
