Problem 1. 1. (4 points) We select a student-athlete from a small private high school at random. Let A be the event { the student-athlete is male } and B be the event { the student-athlete prefers track } . We are told that the proportion of male-athletes who prefer track is the same as the proportion of student- athletes who prefer track ( which then is also the same as the proportion of female-athletes who prefer track ). This statement implies that ( circle one ): A The events A and B are disjoint. B The events A and B are independent. C The events A and B are both disjoint and independent. D The events A and B are neither disjoint nor independent. 2. (4 points) In the same small private high school, sixty-five percent of the student-athletes are male, and are allowed to participate in three varsity sports: football, basketball, and track. However, the female athletes are allowed to participate in only basketball and track. Thirty percent of the student- athletes say that football is their favorite sport in which to compete, while 50% prefer basketball and 20% prefer track. Place this information in the table below.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
