There are 20 children in the cast of a class play, and 8 of the children are boys. Of the boys, 5 have a speaking part in the play, and of the girls, 7 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?

20 children total 8 boys soooo 12 girls

5 boys with speaking parts 5 girls with speaking parts

10 total speaking parts out of 20

10/20 = 1/2 probability
