Here's a three-part puzzler. For each part list the sample space. Listing the sample space will make the probability clear. You can denote Boy as B, Girl as G, and Florida as F when listing a sample space. For example, the sample space of the birth events boy-girl and girl-girl is {BG, GG}.
Your friend has three children. One is a girl named Florida, and one is a girl named Holley. What is the probability that the first child is a boy?
