Solution:Mathematics majors=18

Computer science majors=325

We need to use product rule because the first event is picking the mathematics major and second event is picking the computer science major

18.325=5850


We need to use sum rule because the first event is picking OR mathematics major and second event is picking the computer science major

18+325=343
