8. Show that P(X = k) = kits , for k= -2, -1, 0, 1, 2 and zero elsewhere, is a valid probability distribution for the discrete random variable X. (4 pts) 9. The so-called Expected Value for X is simply equal to the mean value of the probability distribution. Suppose you join a raffle event that will cost you a ticket worth 200 php for a chance to win a grand prize of 10,000 php. You know that there are 500 tickets sold for the event and you want to find out how much will be the pay-off for buying one of the tickets. Let the amount of pay-off be represented by X and solve for the expected-value of your pay-off. (Clue: there are only two possible amounts of pay-off in this scenario. The amount for losing and the amount for winning. Take note of the ticket price) (3 pts)
