Question

Suppose that you flip a coin 23 times. The coin slightly favors heads over tails, so there is a 62% chance that any particular flip comes up heads. Assume that each flip is independent of the others.

 

What is the probability that exactly 18 flips come up heads? 

What is the probability that 18 or more flips come up heads?

What is the probability that fewer than 18 flips come up heads? 

 

(Round each answer to at least four decimal places.)
