In most cases when the lights go out it a minor problem needing only $15 to repair the plan, this happens 55% of the time. About 40% of the time the electrician must do a little bit more work do weather and it cost Elizabeth about $30 to fix the electricity. Very rarely, the electricity problem is severe, and the electrician must dig into the ground. This costs Elizabeth about a $100 to repair. 12) What is Elizabeth expected repair cost? 13) What is the standard deviation for the cost? 14) Suppose that the electrician must add $5 to all the prices, what is the new expected cost and standard deviation?
