The new owner of a beauty shop is trying to decide whether to hire one, two, or three beauticians. She estimates that profits next year (in thousands of dollars) will vary with demand for her services, and she has estimated demand in three categories, low, medium, and high. NUMBER OF BEAUTICIANS DEMAND LOW MEDIUM HIGH One 50 75 100 Two 0 100 100 Three (100 ) 70 300 If she feels the chances of low, medium, and high demand are 50 percent, 20 percent, and 30 percent respectively, what are the expected annual profits for the number of beauticians she will decide to hire?
