Q: If a couple were planning to have three children, the sample space summarizing the gender outcomes would be:
bbb,bbg,bgb,bgg,gbb,gbg,ggb,ggg:
1. Construct a similar sample space for the possible gender outcomes (using b for boy a g for girl) of two children?
2. Assuming that the outcomes listed in part 1 were equally likely, find the probability of getting two boy children?
3. Find the probability of getting exactly one boy child and one girl child?
