At a local high school, 30% of the students are on a school sports team, 25% take at least one Advanced Placement (AP) class, an
d 10% are on a sports team and take at least one AP class. If a student was randomly selected from this school, what is the
probability that the student is on a sports team or takes at least one AP class?
First we have to see in both cases what is the cost of one ticket in the fist case 12.5/5=2.5 in the second case 20.16/8=2.52 therefore 5 tickets for 12.5 is the better deal
