Question

You are given the following distributions, where some of the probabilities have been removed. Complete the tables so that each probability distribution is valid. (Round your answers to two decimal places.)

(Find values of the “?”)

Distribution A Distribution B Distribution C

X P(x) X P(x) X P(x)

1 ? 5 0.22 3 0.7

2 0.6 10 ? 4 0.25

15 0.22 5 ?

20 0.36

Answer 1

The sum of the probabilities for any probability distribution is 1. The missing probability value for each probability distribution will be 1 - the remaining probabilities.
