An unfair coin with​ Pr[H] = 0.75 is flipped. If the flip results in a​ head, a student is selected at random from a class of fifteen boys and ten girls.​ Otherwise, a student from a different class containing five boys and

eight girls is selected.

What is the probability of selecting a​ girl, given the flip resulted in​ heads?
