The probability is 1/2 that a certain coin turns up heads on any given toss. If the coin is tossed six times, what is the probability that the coin turns up tails on at least one of the tosses?  Choose the correct choice from the following answers:	A) 15/16	B) 21/32	C) 31/32	D) 63/64	E) 51/64
P(6 heads)= 1/2*1/2*1/2*1/2*1/2*1/2=1/64.   P(at least one tail)=1-1/64=63/64.   The answer is 63/64.
