Suppose you flip a fair coin six times. What is the probability that, in six flips, you get at least one head?
Choose the most appropriate option.
A) 5/8  B) 13/16  C) 15/16  D) 31/32  E) 63/64
Best way of solving an "at least 1" type of question is to compute "1 - probability of flipping 0 heads"   probability of flipping either a head or a tail = 1/2   probability of flipping 6 tails in a row (1/2)^6   probability of flipping at least 1 head = 1 - (1/2)^6 = 63/64 (answer 63/64)
