23 people attend a party. Each person shakes hands with at least two other people. What is the minimum possible number of handshakes?
23 people must shake hands with 22 other people
this would be 23 x 22 = 506 handshakes BUT two people are involved with each handshake
so 506 /2 = 253 handshakes
I tried putting your answer in to the system but it said that the answer is incorrect.
