Question

Determine the required value of the missing probability to make the distribution a discrete probability distribution. x ​p(x) 3 0.320.32 4 ​? 5 0.180.18 6 0.210.21

Answer 1

To get the required value of the missing probability to make the series complete is to deduct all the probability given to 1 because we know that the discrete probability distribution must be equal to 1. So doing what I have said, this will be:

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

= 1 – 0.3 – 0.18 – 0.21

= 0.31 is the answer.
