On four consecutive flips of a coin, what is the probability that all four produce the same result? Choose the correct choice from the following:
A) 1/16
B) 1/8
C) 1/4
D) 3/8
E) 1/2
TTTT case --&gt; P = (1/2)^4 = 1/16   HHHH case --&gt; P = (1/2)^4 = 1/16   P(TTTT or HHHH) = 1/16 + 1/16 = 2/16=1/8   Answer: 1/8
