What is the formula of nC0?
Therefore nC0=n!/[(n-0)!
What is the formula to calculate the number of handshakes?
# handshakes = n*(n – 1)/2. This is because each of the n people can shake hands with n – 1 people (they would not shake their own hand), and the handshake between two people is not counted twice. This formula can be used for any number of people. For example, with a party of 10 people, find the number of handshakes possible.
How many handshakes are there in one person?
For the first person, there would be N-1 handshakes. For second person there would N-1 person available but he had already shaken hand with the first person. So there would be N-2 handshakes and so on. (using the formula of sum of first N natural number).
How many people does the first person shake hands with?
The first person shakes hands with everybody in the room except for himself. His total number of handshakes is therefore 1 lower than the total number of people. The second person has now shaken hands with the first person, but still needs to shake hands with everybody else.
How many mathematicians in 4851 handshakes?
