Question

An engineering school reports that 57% of its students were male (M), 33% of its students were between the ages of 18 and 20 (A), and that 20% were both male and between the ages of 18 and 20.

What is the probability of a random student being male or between the ages of 18 and 20?

Answer 1

Answer: See explanation

Explanation:

A table has been attached for further information.

The probability of a random student being male or between the ages of 18 and 20 will be:

= P(male)+P(18-20 age) - P(male and 18-20 age)

= 0.57 + 0.33 - 0.20

= 0.70
