The random variable X is the sum of the numbers on which the spinners land. What is P(5≤X≤8) ?

Given:

Spinner 1 = 1, Spinner 2 = 4,5
Spinner 1 = 2, Spinner 2 = 3,4,5
Spinner 1 = 3, Spinner 2 = 2,3,4,5
Spinner 1 = 4, Spinner 2 = 1,2,3,4

There are possibly 13 outcomes.


P(5≤X≤8) = 13/(4*5) = 13/20
