One state lottery has 1,100 prizes of $1; 115 prizes of $10; 25 prizes of $65; 5 prizes of $280; 2 prizes of $1,260; and 1 prize of $2,500. Assume that 33,000 lottery tickets are issued and sold for $1 Question 3What is the lottery's expected profit per ticket? Question 4What is the lottery's standard deviation of profit per ticket?

If a payoff is equally likely to be $1, $2, $3, $4, or $5, the square of the standard deviation is: O 0. Ⓒ 2. O 4. O 10. O 100.
