In a five-person group, there are three girls—Anna, Barbie, and Carol, and two boys—Daniel and Ernesto. Two students will be randomly selected to be a presenter and recorder. If the first person chosen is a girl, what is the probability that two girls will be selected?

OpenStudy (agent0smith):

First girl is already gone so there's one less girl.. so find the probability of a girl being selected now
