One state lottery game has contestants select 5 different numbers from 1 to 45. The prize if all numbersare matched is 2 million dollars. The tickets are $2 each.1) How many different ticket possibilities are there? 45C5 =1,221,7592) If a person purchases one ticket, what is the probability of winning?1 in 1,221,759 = .0000008184920267What is the probability of losing?1-.0000008184920267 = .99999549063) Occasionally, you will hear of a group of people going in together to purchase a large amount oftickets. Suppose a group of 30 purchases 6,000 tickets.a) How much would each person have to contribute? 6000/30 = 200 tickets per person at $2 perticket = 200(2) = $ 400 per person.b) What is the probability of the group winning?6000/1221759=0.004910952Losing? 1-0.004910952 = .9950890484) How much would it cost to "buy the lottery", that is, buy a ticket to cover every possibility? Is itworth it? 2(1221759) = $2,443,5185) Create a probability distribution table for the random variable x = the amount won/lost whenpurchasing one ticket.6) In fair games, the expected value will be $o. This means that if the game is played many...manytimes, then one is expected to break even eventually. This is never true for Casino and Lotterygames. Find the expected value of x = the amount won/lost when purchasing one ticket.

In a larger Business Statistics class, the professor has each person select stocks by throwing 16 darts at pages of the Wall Street Journal. They then check to see whether their stock picks rose of fell the next day and report their proportion of "successes". As a lesson, the professor has selected pages of the Journal for which exactly half the publically traded stocks went up and half went down. The professor then makes a histogram of the reported proportions.a) What shape would you expect this histogram to be? Why?b) Where do you expect the histogram to be centered?c) How much variability would you expect among these proportions?d )Explain why a normal model should not be used here.
