If each of the five members in a basketball team shakes hands with every other members of the team before the game starts,how many handshakes will there be in all?

What is the range of the following:86,70,83,90,85,78,79,81,87?

The range is when you add up all of the points and then divide by how many points you had. (86+70+83+90+85+78+79+81+87)/9= 82

Please don't answer questions if you don't know what you area talking about
the range
= the largest  the smallest
= 90  70
= 20 
Do not use your own "reply" to ask a new question.
number of handshakes = C(5,2)
= 10
