A couple plans to have three children. There are 8 possible arrangments of girls and boys. For example, GGB means the first two children are girls and the third child is a boy. All 8 arrangements are (approximately) equally likely. Report your probability answers as a fraction. (i.e. 2/4 instead of .5) Write down all 8 arrangements of the sexes of three children. What is the probability of any one of these arrangements? Let X be the number of girls the couple has. What is the probability that X = 2? %3D Fill in the missing value in the distribution for X below, beginning with all the values that X can take and then the probabilities. Value of X Probability 3/8
