Question

In a class of 7 students there are 4 that play soccer.

if the teacher picks 3 students what is the probability that none of them play soccer

Answer 1

Explanation:

The total number of ways to draw 3 students is 7*6*5 = 210

Order does not matter. There are 3 students that don't play soccer.

P(3 don't play soccer) = 3*2 * 1 / 210 = 1/35 = 0.02857
