A grocery store is trying to predict how many packages of toilet paper rolls will be purchased over the next week. They know from their records that each customer has a 60% chance of buying 0 packages, a 30% chance of buying 1 package, an 8% chance of buying 2, and a 2% chance of buying 25. They expect about 150 customers per day.

What is the probability that the average number of packages per customer is greater than 1 over the course of a week? Assume the store is open 7 days a week.

Please calculate the standard error.

In the game of​ roulette, a player can place a ​$9 bet on the number 6 and have a 1 /38 probability of winning. If the metal ball lands on 6​, the player gets to keep the ​$9 paid to play the game and the player is awarded an additional ​$315 ​Otherwise, the player is awarded nothing and the casino takes the​ player's ​$9. Find the expected value​ E(x) to the player for one play of the game. If x is the gain to a player in a game of​ chance, then​ E(x) is usually negative. This value gives the average amount per game the player can expect to lose

A marketing firm is considering making up to three new hires. Given its specific needs, the management feels that there is a 60% chance of hiring at least two candidates. There is only a 7% chance that it will not make any hires and a 10% chance that it will make all three hires.

a. What is the probability that the firm will make at least one hire? (Round your answer to 2 decimal places.)

b. Find the expected value and the standard deviation of the number of hires. (Round intermediate calculations to at least 4 decimal places. Round your final answers to 2 decimal places.)

Because you are an avid sports fan, you accepted Ruth's invitation. At the sporting event, Ruth begins talking about Burn's upcoming contract renewals with suppliers. Because there is intense competition and because it is the first bid she will submit to Burn's Corporation, she asks you to review her bid to make sure "it is good enough" before she submits it to the company. In addition, because you are knowledgeable about costs, especially regarding this contract, she asks you to tell her if her bid is "in the ballpark" or "needs improvement." She indicates that if she wins the contract, you will be provided with season tickets for the rest of the year.
