When tossed, a certain coin has equal probability of landing on either side. If the coin is tossed 4 times, what is the probability that it will land on the same side each time?
Options:
(A) 1/8
(B) 1/4
(C) 1/16
(D) 1/2
(E) 1/32 Stream of consciousness:
Must be either 4 tails or 4 heads
1/2*1/2*1/2*1/2+1/2*1/2*1/2*1/2
1/16 + 1/16 = 1/8
Thus, the answer is (A).
