Seven girls and six boys walk into a video store at the same time. There are five salespeople available to help them. Find the probability that the salespeople will first help the given numbers of girl and boys.

Choosing all girls and choosing all boys are mutually exclusive

Therefore in this problem, "OR" means "PLUS"

P(all girls OR all boys) =

P(all girls) + P(all boys) =
