What are the odds of matching all numbers in Keno?

The odds depend on the number pool size, how many numbers are drawn, and how many you pick. For a standard 80/20 game picking 10 numbers, the odds of matching all 10 are approximately 1 in 8,911,711.

How is Keno probability calculated?

Keno uses the hypergeometric distribution. The probability of catching k numbers when picking s from a pool of N with D drawn is: C(D,k) × C(N-D, s-k) / C(N,s), where C is the combination function.

Keno typically has a house edge of 25-40%, making it one of the higher house-edge lottery games. The expected return varies by operator and game format. Always check the specific pay table for the game you are playing.
