The average amount of money a person spends on lottery tickets each month is €8. By looking at the data set, a Poisson discrete distribution is assumed for this variable. Calculate each of the following. a. The probability of buying no lottery ticket. b. The probability of buying 1 lottery ticket. c. The probability of buying 3 lottery tickets. d. The probability of buying fewer than or equal 3 tickets. a. The probability of buying no lottery ticket is approximately (Simplify your answer. Round to six decimal places as needed.)

In a certain lottery, six numbers are randomly chosen form the set {0, 1, 2, ..., 49} (without replacement). To win the lottery, a player must guess correctly all six numbers but it is not necessary to specify in which order the numbers are selected. (a) What is the probability of winning the lottery with only one ticket? (b) Suppose in a given week, 6 million lottery tickets are sold. Suppose further that each player is equally likely to choose any of the possible number combinations and does so independent of the selections of all other players. What is the probability that exactly four players correctly select the winning combination? (c) Again assuming 6 million tickets sold, what is the most probable number of winning tickets? (d) Repeat parts (b) and (c) using the Poisson approximation to the binomial probability distribution. Is the Poisson distribution an accurate approximation?

A lottery is to be conducted in which 10,000 tickets are to be sold for $1 each. Six winning tickets are to be randomly selected: one grand prize winner of $5000, one second prize winner of $2000, one third prize winner of $1000 and three other winners of $500 each. Q16. Let X represent the net winnings of a person who purchases one ticket in the lottery. Obtain the probability distribution of X and compute P(X=-1) a) 0.0003 b) 0.0001 c) 1.00 d) 0.9994 Q17. Compute the expected net winnings from buying a ticket in the lottery. a) 0.05 b) 1.05 c) -0.05 d) -1.05
