The higher the odds, the less likely the event will happen. However, as this prediction is never 100% accurate, there is such a thing as a value bet. A value bet occurs when a punter believes that the odds of an event occurring are greater than the odds assigned by the bookmaker, thus presenting potential opportunities. As odds are an indication of the likelihood of an event or outcome occurring, they are influenced by three factors: The bookmaker’s edge:Online bookmakers include a margin in the odds that ensures their profit. This makes theodds worse than the actual probability of an outcome occurring. Decimal odds represent the total amount you will be paid if the bet wins, including the original stake. To understand the implied probability (probability that the bookmaker believes exists for the event to occur) in decimal odds, the formula is: 1 / Decimal odds Example: 1 / 2.50 = 0.40 (or a 40% chance of the event occurring). Fractional odds represent the potential profit in relation to the bet. Fractional odds are shown as a fraction, i.e., 3/1 or 5/2. To calculate the odds, the formula is Denominator / (Denominator + Numerator).

american odds of 150 = (100 / (150 + 100)) * 100 = 40%. Negative odds - Firstly multiply the american odds by -1 and use the positive value in the following formula: american odds divided by (the american odds plus 100), multiplied by 100 to give a percentage e.g. Decimal - 1 divided by (the percentage divided by 100) e.g. a probability of 50% = 1 / (50 / 100) = 2. Fraction - (1 divided by (the percentage divided by 100)) minus 1 e.g.

a probability of 25% = (1 / (25 / 100)) - 1 = 3 = 3/1. American: Positive odds - (100 divided by (the percentage divided by 100)) minus 100 e.g. a probability of 10% = (100 / (10 / 100)) - 100 = 900.Negative odds - The probability divided by (1 minus (the probability divided by 100)) then multiply by -1 to convert into a negative e.g. a probability of 60% = (60 / (1 - (60/100))) * -1 = -150. Positive odds - (100 divided by (the percentage divided by 100)) minus 100 e.g.

a probability of 10% = (100 / (10 / 100)) - 100 = 900. Negative odds - The probability divided by (1 minus (the probability divided by 100)) then multiply by -1 to convert into a negative e.g. Positive odds - 1 plus (the american odds divided by 100) e.g. american odds of 300 = 1 + (300/100) = 4. Negative odds - 1 minus (100 divided by the american odds) e.g. Example: 2 / (2 + 5) = 0.285 (or 28.5 %). Money Line odds, or American odds, have their own way of representing probability. Positive moneyline odds indicate how much you can win with a $100 bet, while negative odds indicate how much you need to bet to win $100. For example, if the American odds are +200, this means that you would win $200 if you bet $100. For positive odds, the formula is: 100 / (Money line odds + 100). For negative odds, the formula is: Money line odds / (Money line odds + 100). If the moneyline odds are -200, the probability of the event occurring would be: 200 / (200 + 100) = 0.67 (or 67%). The table below shows the relationship between the likelihood of an event, the different types of odds and the potential winnings on a $100 bet.

Note that increasing the probability of an event reduces the odds and potential winnings. A value bet is a bet where you believe that the odds of an event happening are greater than the odds offered by the bookmaker. The value of a bet is calculated using the formula: Value = (Odds * Odds) - 1. If the resulting value is greater than 0, it is considered a value bet. For example, you would make a value bet when you consider a basketball team to have a 60% chance of winning, but the odds offered imply they have only a 40% chance (approximate decimal odds of 2.50). That is: Value = (0.60 * 2.5) - 1 = 1.50 - 1 = 0.50 (being greater than 0 is value).
