QuestionHow many handshakes occur when 4 people shake hands once? Generalize for nn people.

Studdy Solution
To generalize the solution for nn people, we can use the same formula for combinations. The number of handshakes is the same as the number of ways to choose2 people out of nn to shake hands.
So, the general formula for the number of handshakes isC(n,2)=n!2!(n2)!C(n,2) = \frac{n!}{2!(n-2)!}
