If there are N people in a room and everyone needs to shake everyone else’s hand, how many handshakes are going to occur? Three groups will be selected at random to present their solutions...In your explanations be sure to include EACH step of the problem solving process. Be sure you can EXPLAIN your reasoning. If your group is selected and you do not present, you will receive a grade of 0 on this presentation…
