What are the odds in favor of getting at least one head in three successive flips of a coin?
Can someone help me figure out how to solve this, please?
YOu could get
7 ways to get at least one head, and the probability of getting each one of those is 1/2*1/2*1/2 or 1/8
Pr= 7/8 getting at least one head.
