Probability Distributions of discrete Random Variables:
You set up a carnival booth at a local fund-raising event. The game consists of a giant six sided fair die and costs $3.00 per roll. If they roll a 6, they win a prize that costs $8.00. If they roll a 1, they win a prize that costs $2.50. Otherwise, they do not win anything. If you average 35 participants per hour for 8-hour event, how much money do you expect to raise during the event?
