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 has estimated demand in three categories low, medium and high

NUMBER OF BEAUTICIANS DEMAND

$---------------------------$ LOW MEDIUM HIGH

$-$ One $5075100$

Two $0100100$

Three $-10070300$

If she feels the chances of low, medium, and high demand are $50\%,20\%,$ ?and $30\%$ ?respectively, what are the expected annual profits for the number of beauticians she will decide to hire?
