The functions f and g are differentiable for all real numbers and g is strictly increasing. the table above gives values of the functions and their first derivativs

im not sure of the names, but the answer is 48

in counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: httt, thtt, ttht, or ttth. each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.
