Cystic fibrosis is a recessive trait in humans.

a. If two people are heterozygous for cystic fibrosis and they have 3 kids, what is the probability that one of these will have cystic fibrosis?

b. What is the probability that only the first child will have cystic fibrosis?

c. What is the probability that they will have 2 normal sons and 1 daughter with cystic fibrosis?

No order is specified on any. Please show all the work so I can better understand the process of getting the answer. Will need to do this in the future.
