Part B Assume that in a 6-day weeklong trip during the month of February at a ski resort, the probability of snow on any day is 0.3 Required: a) What is the probability that snow will fall on exactly 3 days of a weeklong trip to that ski resort in February? b) What is the probability that snow will fall on at most 1 day of a weeklong trip to that ski resort in February? c) What is the probability that snow will fall on at least 2 days of a weeklong trip to that ski resort in February? Find the expected value and the variance of the random variable x.
