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.) Distribution A Distribution B Distribution C x P(x) x P(x) x P(x) 1 5 0.22 3 0.7 2 0.8 10 4 0.25 15 0.22 5 20 0.339999999999
