A brokerage survey reports that 27% of all individual investors have used a discount broker (one that does not charge the full commission). If a random sample of 80 individual investors is taken, approximate the probability that more than 18 have used a discount broker. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)

Suppose that you are offered the following "deal." You roll a six sided die. If you roll a 6, you win $12. If you roll a 3, 4 or 5, you win $5. Otherwise, you pay $6.a. Complete the PDF Table. List the X values, where X is the profit, from smallest to largest. Round to 4 decimal places where appropriate. X P(X) b. Find the expected profit. $ (Round to the nearest cent)c. Interpret the expected value. This is the most likely amount of money you will win. You will win this much if you play a game. If you play many games you will likely win on average very close to $2.50 per game. d. Based on the expected value, should you play this game? Yes, since the expected value is 0, you would be very likely to come very close to breaking even if you played many games, so you might as well have fun at no cost. No, this is a gambling game and it is always a bad idea to gamble. Yes, since the expected value is positive, you would be very likely to come home with more…
