Possible values of X, the number of components in a system submitted for repair that must be replaced, are 1, 2, 3, and 4 with corresponding probabilities 0.05, 0.45, 0.05, and 0.45, respectively. (a) Calculate E(X) and then E(5 − X). (b) Would the repair facility be better off charging a flat fee of $100 or else the amount $[150 / (5 - X)]? What is E[150 / (5 - X)]?

If x is the net 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 over the long run. A service organization is selling $3 raffle tickets as part of a fundraising program. The first prize is a boat valued at $2960, and the second prize is a camping tent valued at $400. In addition to the first and second prizes, there are twenty-two $25 gift certificates to be awarded. The number of tickets sold is 3000. Find the expected net gain to the player for one play of the game. Round your answer to the nearest cent.
Use the information to answer the following questions. To calculate the risk premium on government bonds we use the formula. (1 + i) = (1 – p) (1 + i + x) + p(0) Where p is the probability that the bond does not pay at all (the bond issuer is bankrupt) and has a zero return, i is the nominal policy interest rate and x is the risk premium. a. If the probability of bankruptcy is zero, what is the rate of interest on the risky bond? (1) b. Calculate the probability of bankruptcy when the nominal interest rate for a risky borrower is 8% and the nominal policy rate of interest is 3%. (3) c. Calculate the nominal

In baseball there are many ways to estimate what a team's winning percentage (w) should be against its opponents, given the total runs it has scored and the total runs it has allowed in a certain number of games. Bill James's Pythagorean Formula for the winning percentage estimator is given below. wpe = w = [(# runs scored)2]/[(# runs scored)2 + (# runs allowed)2] A team has currently scored 369 runs and allowed 329 runs. If the team does not allow any more runs for the rest of the season, how many additional runs must they score in order to have a wpe of 80%? (Hint: Let x = the number of runs additional scored.)

Two investments, X and Y, have the characteristics shown below. E(X) = $60, E(Y) = $90, o = 10,000, o? = 17,000 and axy = 6,500 If the weight of portfolio assets assigned to investment X is 0.8, calculate the a. portfolio expected return and b. portfolio risk. a. If the weight of portfolio assets assigned to investment X is 0.8, the portfolio expected return is $ (Type an integer or a decimal.) b. If the weight of portfolio assets assigned to investment X is 0.8, the portfolio risk is approximately $. (Round to two decimal places as needed.)
Do you have to be rich to invest in bonds and real estate? No, mutual fund shares are available to you even if you aren't rich. Let x represent annual percentage return (after expenses) on the Vanguard Total Bond Index Fund, and let y represent annual percentage return on the Fidelity Real Estate Investment Fund. Over a long period of time, we have the following population estimates. Hx = 7.34, Ox = 6.55, Hy = 13.15, Oy = 18.55, p z 0.424 (a) Do you think the variables x and y are independent? Explain your answer. o Yes. Interest rate probably affects both investment returns. o No. Interest rates probably has no effect on the investment returns. o No. Interest rate probably affects both investment returns. o Yes. Interest rates probably has no effect on the investment returns. (b) Suppose you decide to put 60% of your investment in bonds and 40% in real estate. This means you will use a weighted average w = 0.6x + 0.4y. Estimate your expected percentage return uw and risk ow. Pw = Ow =…
