Question

A 6-sided die has been weighted so that certain numbers are more likely to be rolled than others. Let the random variable, X, represent the number rolled. The chance for each number is given in the probability distribution below. Find E(X), the expected number rolled on a single roll. Round your answer to two decimal places. X | P(X = x) 1 | 0.031 2 | 0.103 3 | 0.184 4 | 0.076 5 | 0.219 6 | 0.387
