Determine the required value of the missing probability to m

Determine the required value of the missing probability to make the distribution a discrete probability distribution.

x

            P(x)

3

            0.28

4

                 ?

5

            0.36

6

            0.14

P(4) = ______

(Type an integer or a decimal)

Solution

The required missing probability is: 1-(0.28+0.36+0.14)=0.22

The total probability is 1.
