Question

In a group of 150 people, 39 of them wear glasses. What is the probability of randomly selecting a person who does not wear glasses?

A. 111/150
B. 39/111
C. 111/189
D. 189/150
E. 39/150

Answer 1

A. 111/150

Explanation:

Because we know that 39 people out of the 150 in the group wear glasses, we need to subtract that from the total. This gives us 111 people that don't wear glasses.

Therefore, the probability of choosing someone not wearing glasses is 111/150.
