Question

In a class of 32 students, what is the probability of finding exactly 4 left-handers?

Answer 1

1.25% chance of finding exactly 4 left-handers

Explanation:

About 10% of people are left-handed. So in a class with 32 students:

1 / 10 * 4/32 = 1/10 * 1/8

1/10 * 1/8 = 1/80 = 0.0125 = 1.25%
