An Olympic archer is able to hit a bulls-eye 80% of the time. Assume each shot is independent of the others. If she shoots 7 arrows, what is the probability of each result described below? a. What is the expected number of bulls-eyes for the 7 attempts? b. What is the standard deviation? c. She gets at least 4 bulls-eyes? d. Make a histogram showing the probability that r = 0, 1, 2, 3, 4, 5, 6, 7 bulls-eyes?

A) An Olympic archer is able to hit the bull’s eye 80% of the time. Assume each shot is independent of the others. She will shoot 6 arrows. Let X denote the number of bull’s eyes she makes. Find the mean of the probability distribution of X. Do not round B) The GPA of students at a college has a mean of 2.9 and a standard deviation of 0.3. Scores are approximately normally distributed. Suppose that the top 6% of...

Imagine an archer is able to hit the bull’s-eye 82% of the time. Assume each shot is independent of all others. If the archer shoots 10 arrows, then the probability that every arrow misses the bull’s-eye is a value between: ? In problem above: The expected value of the number of arrows that hit the bull’s-eye, is exactly equal to: ? In problem above: The probability that the archer hits the bull’s-eye more often than they miss, is a value...

An Olympic archer misses the bull's-eye 13% of the time. Assume each shot is independent of the others. If she shoots 9 arrows, what is the probability of each of the results described in parts a through f below? a) Her first miss comes on the fourth arrow. The probability is 9.8. (Round to four decimal places as needed.) b) She misses the bull's-eye at least once. The probability is 0.6731. (Round to four decimal places as needed.) c) Her...

A firm has $100 in cash and debt of $80. Assume that the time value of money is zero. A novel project comes along that costs $60 and that will either deliver $0 or x with equal probabilities 1. What is the value of debt and equity without the project? 2. What is the x value above which the project would be positive NPV? Call this xh 3. What is the x value above which the shareholders want the firm...

Assume a firm has cash of $10 and a project that is either worth $130 or $80 (50% chance of each). The firm owes $110 to the bank. Similar to the example in class, the following shows the value of assets, debt, and equity where the amounts are calculated based on expected values. Cash $10 Debt $100 Project $105 Equity $15 Total $115 Total $115 Assume the firm is considering a new project which requires an initial investment of $5....
