Answer:
10 handshakes
Step-by-step explanation:
Five people come to a party and shake hands with each other.
This means 5 people shakes the hand of other 4 persons.
We use the formula [tex]\frac{n(n-1)}{2}[/tex]
Where n is number of people
[tex]\frac{5(5-1)}{2}[/tex]
[tex]\frac{20}{2}[/tex]
= 10
10 handshakes would occur.
