In families with four children, you're interested in the probabilities for the different possible numbers of girls in a family. Using theoretical probability (assume girls and boys are equally likely), compile a five-column table with the headings "0" through "4," for the five possible numbers of girl children in a four-child family. Then, using "G" for girls and "B" for boys, list under each heading the various birth-order ways of achieving that number of girls in a family. Then, use your table to calculate the following probabilities:
a. The probability of 1 girl 1/5=0.2 (20%) 20%
b. The probability of 2 girls 1/5=0.2 (20%) 20%
c. The probability of 4 girls 1/5=0.2 (20%) 20%
d. The probability the third child born is a girl Out of the five possible outcomes, four of them have the probability to have the third child being a girl. 4/5=80/100 80%
