There will be 231 handshakes in total
<em><u>Solution:</u></em>
There are 22 people in a room
Everyone shakes everyone else’s hand exactly one time
<em><u>To find: Total number of handshakes in total</u></em>
Let,
n = total number of people that will shake hands
but since all (total) can't shake hands with themselves, hence we subtract one individual to start the handshaking
(n - 1) = people would each shake hands
hence we multiply both total number persons with people that will shake hands;
n(n - 1)
but that counts every handshake twice, so we have to divide by 2
Therefore;
Here, n = 22
Thus there will be 231 handshakes in total
