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 = .8184920267what is the probability of losing? 1-.8184920267 = .549063) 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 times, 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.
