High school students in Michigan sometimes get "snow days" in the winter when the roads are so bad thatschool is canceled for the day. Define the random variableX = the number of snow days at a certain high schoolin Michigan for a randomly selected school year. Suppose the table below gives the probability distribution of X.1.Value x,1.345678910Probability p, ? 0.19 0.14 0.10 0.07 0.05 0.04 0.04 0.02 0.01 0.01(a) Write the event “the school year has O snow days" in terms of X. Then find its probability.(b) At this high school, if more than 5 snow days are used over the course of the year, students are required tomake up the time at the end of the school year. What's the probability that a randomly selected school year willrequire make-up days?

Random variables are of 2 types, discrete and continuous. A discrete random variable can only take…

A psychologist determined that the number of sessions required to obtain the trust of a new patient is either 1, 2, or 3. Let x be a random variable indicating the number of sessions re- quired to gain the patient's trust. The following probability function has been proposed. f(x) = for x = 1, 2, or 3 6. Is this probability function valid? Explain. b. What is the probability that it takes exactly two sessions to gain the patient's trust? с. What is the probability that it takes at least two sessions to gain the patient's trust?
