Let event X be studying 10+ hours.
Let event Y be getting an A on this exam.
Suppose that the probability of getting an A on this exam conditional on studying 10 or more hours is 0.96.Suppose that 13% of students study 10 or more hours. Also suppose that the probability of getting an A on this exam given that you did not study 10 or more hours is 0.83.
What's the probability that you did study 10 or more hours given that you got an A on the exam? (Hint: use Bayes' Theorem and the relative frequency method of assigning probabilitiesto solve.)
