Your aunt is excited that she is pregnant. She wants to know the probability of having a girl. We know that the probability of having one gender or the other is theoretically 0.5 since there are only two genders. If your aunt plans on having 6 children total, what is the expected value of having daughters?

Resource: Question

Question Type: Multiple Choice - Single Answer

Standard(s):HSS.MD.A.3

Standard Description: Develop a probability distribution for a random variable defined for a sample space in which theoretical probabilities can be calculated; find the expected value. For example, find the theoretical probability distribution for the number of correct answers obtained by guessing on all five questions of a multiple-choice test where each question has four choices, and find the expected grade under various grading schemes.
