Quizplus · Accepted Answer

The mean of a discrete probability distribution is calculated by multiplying each value of the variable (x) by its corresponding probability (P(x)) and then summing all these products. For the given distribution, the mean is calculated as follows: Mean = (3 * 0.03) + (6 * 0.2) + (7 * 0.32) + (12 * 0.45) = 0.09 + 1.2 + 2.24 + 5.4 = 8.93.
