2. Joe runs a carnival game in which he charges $2 for a player to randomly select 3 cards from a 52 card deck. If the player gets 3 cards of the same color, the player is handed a $5.00 bill. What is Joe's expected profit per play? (Round to th nearest cent).

3. Suppose a random sample of size n=144 is obtained from a population with a population mean 75 and population standard deviation 10. Use the central limit theorem to approximate the probability P(72 < x bar < 78), where x bar denotes the sample mean.

Sorry, I'm not sure how to do these problems. Much thanks!
