5.20 There are 100 males and 120 females in the graduating

class of a local high school. Thirty-five percent of

the graduating males are on school sports teams, as are

30% of the graduating females. A local businessperson

is going to donate $1000 to the favorite charity of a

randomly selected graduate. What is the probability that

the graduate selected will be a male who is not a member

of a sports team? What is the probability that the

graduate will be either a female or a member of a sports

team?
