Quizplus · Accepted Answer

The expected value of a discrete random variable is equal to the sum of each possible value multiplied by its probability. Using the given probability distribution, we can calculate the expected value as follows:

(0)(0.4) + (1)(0.35) + (2)(0.15) + (3)(0.1) = 1.65

Therefore, the statement is true.
