Question

In a class of 14 girls and 28 boys what is the difference between the probability of picking a boy and the probability of picking a girl

Answer 1

Since there are twice as many boys as girls, the probability of picking a boy, 2/3, is twice the probability of picking a girl, 1/3.

Explanation:

14 girls and 28 boys

total = 14 + 28 = 42

p(girl) = 14/42 = 1/3

p(boy) = 28/42 = 2/3

Since there are twice as many boys as girls, the probability of picking a boy, 2/3, is twice the probability of picking a girl, 1/3.
