experience shows that a ski lodge will be full(181 guests) if there is a heavy snowfall in december, white only partially full guests(88 guests) with a light snow fall. what is the expected number of guests of the probability for a heavy snow fall is .40
i don't know how to get the answer
To determine the expected number of guests for a heavy snowfall with a probability of 0.40, we can use the concept of expected value. The expected value is calculated by multiplying each outcome by its probability and summing them up.
In this case, we have two possible outcomes: a heavy snowfall with 181 guests and a light snowfall with 88 guests.
Expected Value = (Outcome1 * Probability1) + (Outcome2 * Probability2)
Expected Value = (181 * 0.40) + (88 * (1 - 0.40))
Expected Value = (181 * 0.40) + (88 * 0.60)
Expected Value = 72.4 + 52.8
Expected Value = 125.2
Therefore, the expected number of guests when the probability of a heavy snowfall is 0.40 is 125.2 guests.
