Question

A group of 12 male and 8 female students is talking about going out for pizza. If 50% of the male students actually go and 25% of the female students actually go, find the probability that a randomly chosen student is female, given that she is among those who go out for pizza.

Answer 1

1/4

Explanation:

12*50%=12*0.5=6 males

8*25%=8*0.25=2 females

2+6=8

2 out of 8 students are female

2/8=1/4
