Suppose you flip a fair coin 8 times. What is the probability that, in 8 flips, you get at least one head? Choose one:
A) 55/256
B) 255/256
C) 155/256
D) 5/256
E) 201/256
255/256est 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)^5   probability of flipping at least 1 head = 1 - (1/2)^8 = 255/256   Answer : 255/256
