How to Calculate Lottery Probability

The mathematics behind every lottery game.

The math behind lottery odds is actually quite simple. Learn how to calculate the odds of any lottery game and see the numbers in action with Lottist.

nCr Combination formula

49 Max numbers in 6/49

6 Numbers you pick

13.9M Total combinations

The Basic Formula

Lottery probability is calculated using the combination formula: nCr = n! / (r! × (n-r)!). For 6/49, this means 49! / (6! × 43!) = 13,983,816. This tells us the total number of possible combinations, and the chance of winning is 1 in that number.

Understanding Factorials

A factorial (written as n!) means multiplying all numbers from 1 to n. So 5! = 5×4×3×2×1 = 120. Factorials get very large very quickly, which is why lottery odds become astronomical.

Why do lottery odds get so big so quickly?

It's the mathematics of combinations. With each additional number in the pool, the number of possible combinations grows exponentially. This is why 6/49 has 13.9 million combinations, but 7/50 would have over 99 million. Lottist helps you see this math in action.
