Consider normal skin pigmentation

Consider normal skin pigmentation (A) dominant to albino (a) and susceptibility to migraine headache (M) dominant to normal (m). The loci are autosomal. Assume that both parents are heterozygous for the skin colour and migraine traits described above.

a) What is the probability they will have children in the following order: normal skin and no migrane, normal skin and migrane, albino and migraine?

b) What is the probability that their first child will be a girl who does not suffer from migrane?
