To claim his or her prize, a prospective customer needed to present the flier at the dealership’s showroom. The fine print on the back of the flier listed the probabilities of winning. The chance of winning the car was 1 out of 31,748, the chance of winning the gas card was 1 out of 31,748, and the chance of winning the shopping card was 31,746 out of 31,748.How many fliers the automobile dealership sent out? Please explain. Using your answer to above and the probabilities listed on the flyer, what is the expected value ofthe price won by a prospective customer receiving a flyer? Demonstrate all necessary steps. Using your answer to the first question and the probabilities listed on the flyer what is the standarddeviation of the value of the price one by the…
