Problem #1: Hello !!
In a group of 6 students, if each person says ‘hello’ to each of the other group members 1 time, how many total ‘hellos’ will be said in the group?
"What If?"
There are only 2 students?
3 students?
5 students?
7 students?
10 students?
n students?
Rather than "hellos", what if you counted handshakes?
