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

2. You Dont Need To Know My Duuuude

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

3. Reiny

the range
= the largest - the smallest
= 90 - 70
= 20

4. Reiny

number of handshakes = C(5,2)
= 10
