Continuous Probability Distribution Problems The problems here deal with wait times for a ride at Disneyland, with the average wait time being 107 minutes and the standard deviation of those wait times is 30.4. Given X~N(107,30.4), solve the following problems: • What is the probability of waiting less than 45 minutes P(X<45) Z = (45-107)/30.4 = -2.04 P(Z140) Z = (140-107)/30.4 = 1.09 P(Z>1.09) = 1-P(Z<1.09) = 1-0.8621 = 0.1379 Alternatively, you can look up P(Z
