Solution 1

The expected value (E) of a probability distribution is calculated by multiplying each outcome (x) by its probability (P(x)), and then summing these products.

So, for the given distribution, the expected value would be calculated as follows:

E = (-20 * 3/20) + (-10 * 1/5) + (30 * 1/2) + (75 * 1/1 Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
