You can put this solution on YOUR website! Experience shows that a ski lodge will be full (156 guest) if there is a heavy snow fall in December, while only partially full (57 guest) with a light snow fall. What is the expected number of quests if the probability for a heavy snow fall is .40?
------
Random # values: 156 and 57
Corresponding probabilities: 0.6 and 0.4
-----
E(x) = 0.6*156 + 0.4*57 = 116.4
------------
