Each boy shook hands 11 times which would be 132 handshakes but two boys were involved in each therefore 66. Other method: Boy 1 shakes with 11 others, boy 2 has already shaken with boy 1 so has to shake with 10 others and so on. 11 + 10 + 9 ....+ 3 + 2 + 1 = 66
How many handshakes if 49 people shake hands with every other person in room?
48+47+46.......+2+1 = 1176another way:? 49 x 48 ÷ 2 = 49 x 24 = 1176(Each of the 49 people shakes hands with 48 other people:? 49 x 48A shaking B's hand and B shaking A's hand is the same handshake:? ÷ 2)
12 members were present at a board meeting each member shook hands with all of the other members before and after the meeting how many hand shakes were there?
66. Each of the 12 members shook hands with the 11 other people. That would make 12*11 hand shakes. BUT, the A shaking B's hand is the same event as B shaking A's hand so all these handshakes are double-counted. The actual number is half that ie 33. If you are more familiar with combinatorial mathematics, the answer is the number of combinations of two obejects from 12, which is 12C2 = 12*11/(2*1)

Everyone shakes hands with 4 other people. Since there are 5 people in the room this would suggest there are 5*4 = 20 handshakes. However, you would then be double counting handshakes: A shaking hands with B and B shaking hands with A is, in reality, only one handshake. Thus there are 5*4/2 = 10 handshakes in all.
