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 0.26

4 ?

5 0.28

6 0.18

P(4) =

TYPE AN INTEGER OR A DECIMAL.

Solution

P(4) = 1 - (P(3) + P(5) + P(6))

        = 1 - ( 0.26 + 0.28 + 0.18)

        = 0.28 (ANS)
