In humans, the ability to taste PTC is inherited as a dominant gene (T; Taster). in a marriage between two heterozygous tasters (Tt):

a) what is the probability of 3 taster children?

b)what is the probability of 3 taster girls?

c)if they have 5 children, what is the probability that the first 3 will be tasters and the last 2 nontasters?
