Question

There are 20 children in the cast of a class play, and 8 of the children are boys. Of the boys, 4 have a speaking part in the play, and of the girls, 8 do not have a speaking part in the play. If a child from the cast of the play is chosen at random, what is the probability that the child has a speaking part?

a)2/5
b)1/2
c)3/5
d)3/4

Answer 1

A0 2/5

Explanation:

First, find out how many girls there are by subtracting 8 (boys) from 20 (total). This means there are 12 girls. Since 8 girls aren't speaking, 4 are. 4+4=8. 8 out of the 20 children are speaking/ 8/20 simplified is 2/5
