fires his rifle 4 times at the tar? The probability that Mr. Wesson, a rifleman, will hit a target is 0.80. He fires his rifle 4 times at the target. Assuming a binomial distribution, what is the probability that he hits the target exactly 2 times?
Answer

0.1536
0.2596
0.4096
0.5000

P(x = 2) = 4C2 * .8^2 * .2^2

P(x = 2) = 0.1536
