Question

What is the probability that a person chosen at random from this group has brown or green eyes?

3 /25

7 / 25

13 /25

17 .25

Answer 1

13/25

Explanation:

Firstly, we add the total number of persons together

That would be 20 + 6 + 17 + 7 = 50

The number of persons with brown eyes = 20

The number of persons with green eyes = 6

Probability of selecting someone with brown eyes = 20/50

Probability of selecting someone with green eyes = 6/50

The probability of selecting someone with brown or green eyes = Probability of selecting someone with brown eyes + Probability of selecting someone with green eyes = 20/50 + 6/50 = 26/50 = 13/25
