Following an experiment, Jamie estimates that his probability of making a three-pointer with a basketball is 0.8. If he shoots 160 attempts from the three-point line, how many times can he expect to make a three-point basket?
A.
32
B.
80
C.
128
D.
160
The expected value, or mean, is found by multiplying the probability of success by the number of trials:
E(X) = 0.8 x 160 = 128
Therefore, Jamie can expect to make a three-point basket 128 times. Answer: C.
