The probability that a person will remember between 100a% and 100 b% of material learned in an experiment is p a , b = ∫ a b 15 4 x 1 − x d x where x represents the proportion remembered. (See figure.) (a) For a randomly chosen individual, what is the probability that he or she will recall between 50% and 75% of the material? (b) What is the median percent recall? That is, for what value of b is it true that the probability of recalling 0 to b is 0.5?
