Question

A certain lottery​ game, 32 numbers are randomly mixed and 7 are selected. A person must pick all 7 numbers to win. Order is not important. What is the probability of​ winning?

Answer 1

Below.

Explanation:

The number of combinations of 7 from 32 = 32! / 7! (32-7)!

= 3365856

So it is 1/ 3365856 = 0.000000297

or about 3 in 10,000,000.
