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?

Answer 1

The probability of choosing a child with a speaking part is 2/5. This is because 8/20 children have speaking parts, which can be reduced to 2/5, .4, or 40%.
