Question 1

What are decimal odds?

Accepted Answer

Decimal odds represent the total payout per unit staked, including your stake. For example, odds of 2.50 mean you receive KES 2.50 for every KES 1 staked — a profit of KES 1.50.

Question 2

How do I convert fractional odds to decimal?

Accepted Answer

Divide the numerator by the denominator and add 1. For example, 3/2 = 3÷2 + 1 = 2.50 decimal odds.

Question 3

What is implied probability in betting?

Accepted Answer

Implied probability is the bookmaker's estimate of an event's likelihood, derived from the odds. It equals 1 ÷ decimal odds × 100%. Higher implied probability means the bookmaker considers the outcome more likely.

Question 4

What is the bookmaker margin (overround)?

Accepted Answer

The overround is the sum of all implied probabilities in a market, expressed as a percentage above 100%. A market with 105% overround means the bookmaker has built in a 5% profit margin.

Question 5

What is the difference between American and decimal odds?

Accepted Answer

American odds show profit relative to a KES 100 stake (positive for underdogs, negative for favourites). Decimal odds show total return per unit staked. Most Kenyan bookmakers use decimal odds.
