Question

About one-fifth of the population of a town has blue eyes. About two-sevenths of the population has brown eyes. What is the probability that a person chosen at random from this town has blue eyes or brown eyes?

3/13

23/35

1/35

17/35

Answer 1

Answer:

Option C, 1/35

Step-by-step explanation:

Given

Proportion of town that has blue eyes = 1/5 = 0.2

Proportion of town that has brown eyes = 1/7

The probability of choosing either a blue eye or a brown eye person is

Probability of blue eye individual * Probability of brown eye individual

= 1/5 * 1/7 = 1/35

Hence, option C is correct
