Suppose you flip a fair coin three times. What is the probability that, in three flips, you get at least one head?  Choose the correct option
A) 15/8 B) 7/8 C) 13/8 D) 3/8 E) 1/8
7/8est 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 3 tails in a row (1/2)^3   probability of flipping at least 1 head = 1 - (1/2)^3 = 7/8   Answer : 7/8
