There were 5 babies born at a hospital in one day. One baby was male and four were female. If a baby is as likely to be a male as a female, find the probability of this outcome by expanding (m +f)5. Round to the nearest percent if necessary.

Answer:

If four babies are born in a given hospital on the same day, the outcome that all four will be boys is

1/2^4=1/16

The outcome that three will be boys and one a girl would be 4x1/2^3x1/2=1/4

the outcome that two will be boys and 2 will be girls is

6x1/2^2x1/2^2=3/8
