Organizers of a concert are limiting tickets sales to a maximum of 444 tickets per customer. Let T be the number of tickets purchased by a random customer. Here is the probability distribution of T: T=# of tickets P(T) Calculate the expected value of T. 2 0.3 3 0.2 4 0.1 0.4 2. Choose the best interpretation of the mean (or expected value) that you found in the previous question. a. Most customers will purchase 3 tickets. b. A group of 10 customers will purchase exactly 29 tickets. c. If we look at a large number of customers, then each customer, on average, will have purchased about 2.9 tickets. 3. Calculate the standard deviation of T. Round your answer to three decimal places.
