Two Basic Rules of Probability · Exercise 29
At a college, 72% of courses have final exams and 46% of courses require research papers. Suppose that 32% 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.
