Two Basic Rules of Probability · Exercise 29
At a college, 72 percent of courses have final exams and 46 percent of courses require research papers. Suppose that 32 percent of courses have a research paper and a final exam. Let F be the event that a course has a final exam. Let R be the event that a course requires a research paper.
(a) Find the probability that a course has a final exam or a research project.
(b) Find the probability that a course has neither of these two requirements.
