The function f (x) = kx n (1 - x) m , 0 x 1
Question:
The function f (x) = kxn (1 - x)m, 0 ≤ x ≤ 1 where n > 0, m > 0, and k is a constant, can be used to represent various probability distributions. If k is chosen such thatthen the probability that x will fall between a and b (0 ≤ a ≤ b ≤ 1) isThe probability that a person will remember between 100a% and 100b% of material learned in an experiment is
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?
