Assuming that boy and girl babies are equally​ likely, what would be​ Kathy's probability of having at most three daughters if she were to have four children​ altogether? (You may want to use a tree diagram to construct the sample​ space.)

Solutions

Expert Solution

P(girl) = 0.5

n = 4

P(at most 3 daughters) = 1 - P(all 4 are boys) = 1 - 0.54 = 1 - 0.0625 = 0.9375 (ans)
