The maths
Combinations, probabilities and why 17 correct results is as rare as it is.
- The odds of winning a 17 game jackpot in Kenya, worked out
A 17 game 1X2 jackpot has 129,140,163 possible lines, so one blind line wins 1 in 129,140,163. What favourites, pools and slip length change.
- Jackpot combinations and probability: how to calculate them
To calculate a jackpot probability, multiply the chance of each leg. How 1X2 and double chance change the count, and what a 60% favourite does.
- Double chance vs 1X2 in jackpots: the probability, leg by leg
Two outcomes per leg against three: 2^n vs 3^n combinations for 10 to 17 legs, what double chance cover costs, and how fewer outcomes change prizes.
