## The state of Georgia has several statewide lottery options. One of the simpler ones is a "Pick 3" game in which you pick one of the 1000 three-digit numbers between 000 and 999. The lottery selects a three-digit number at random. With a bet of \$1, you win \$470 if your number is selected and nothing (\$0) otherwise.(a) With a single \$1 bet, what is the probability that you win \$470?(b) Let X denote your winnings for a \$1 bet, so x = \$0 or x = \$470. Construct the probability distribution for X. Use 3 decimal places.X P(X)\$0 \$470(c) The mean of the distribution equals \$(d) Would this be considered a gain for you?No. For every \$1 I pay, I will lose \$ 0.53 on average.No. For every \$1 I pay, I will lose \$0.47 on average.Yes. For every \$1 I pay, I will win \$0.47 on average.(e) If you play "PICK 3" 100 times, how much should you expect to lose? \$
