For one toss of a certain coin, the probability that the outcome is heads is 0.8. If this coin is tossed 5 times, which of the following is the probability that the outcome will be heads at least 4 times? Choose the correct choice from the following:
A) (0.8)^5  B) 2(0.8)^4  C) 3(0.8)^4  D) 4(0.8)^4(0.2) + (0.8)^5  E) 5(0.8)^4(0.2) + (0.8)^5
P(5 heads) = (0.8)^5   There are 5 ways to get 4 heads: HHHHT, HHHTH, HHTHH, HTHHH, THHHH   P(4 heads) = 5*(0.8)^4(0.2)   The answer is 5(0.8)^4(0.2) + (0.8)^5.
