>Assuming that the phenotypes of two randomly selected individuals are independent of each other, what is the probability that both phenotypes are O?
I'm simply multipling (45/100) * (44/99) and get .2 however the answer is .1936
What am I doing wrong?
Should it be something like (99 nCr 44 / (45 nCr 100) + (98 nCr 4 / 44 nCr 99) ?
