A certain brand of upright freezer is available in threedifferent rated capacities: 16 ft3, 18 ft3, and 20 ft3. LetX = the rated capacity of a freezer of this brand sold ata certain store. Suppose that X has pmf x 16 18 20 p(x) 0.2 0.5 0.3 a. Compute E(X), E(X2), and V(X). b. If the price of a freezer having capacity X is70X - 650, what is the expected price paid by thenext customer to buy a freezer? c. What is the variance of the price paid by the nextcustomer? d. Suppose that although the rated capacity of a freezeris X, the actual capacity is h(X) = X - 0.008X2. Whatis the expected actual capacity of the freezer purchased by the next customer?
Assume the stock price follows a geometric Brownian motion, where current price S0=50, expected return µ=0.02 and volatility σ=0.80. The risk-free interest rate r=0.05 p.a. Using the Black-Scholes formula, what is the current value c0 of an European call option written on the stock with a strike of K=50 and a maturity of 3 months?
You consider investing £800 in stocks of the company X for a certain period. There is a possibility for X to merge with Y, in which case you expect your investment to appreciate £300, otherwise you expect it to depreciate £200. Also, rather than investing, you can choose to keep your £800. By using a utility function U(x)=x−−√, and by defining pthe probability that X merges with Y, what is the condition that p must satisfy for your investment to be worthwhile (rounded to two decimal places)?
Theorem 6.4 states that the moment-generating function of the gamma distribution is given by Mx(t) = (1-βt)^(-α).
The following facts about a company are known: 1. At present, its total capital is £3 million. 2. It has just sold zero-coupon bonds with the total nominal value of £2 million which it promises to repay in 18 months from now. 3. The total capital F(t) of the company follows the geometric Brownian motion with parameters µ = 0.15 and σ = 0.2. The continuously compounded annual interest rate r = 6%. Within the framework of the Merton model, establish the following. (c)What is the probability that the company would default on its promise to bond holders?
If X is exponentially distributed with parameter λ and Y is uniformly distributed on the interval [a, b], what is the moment generating function of X + 2Y ?
1. Let f (x) = cx 3 and S X = [0, 2] (X is continuous and c is a constant) a. Find the expectation of X, E(X).b. What is P (0.5 < X < 1.5)?c. What is P (0.5 < X < 2.5)?
A life insurance salesman operates on the premise that the probability that a man reaching his sixtieth birthday will not live to his sixty-first birthday is 0.050.05. On visiting a holiday resort for seniors, he sells 1010 policies to men approaching their sixtieth birthdays. Each policy comes into effect on the birthday of the insured, and pays a fixed sum on death. All 1010 policies can be assumed to be mutually independent. Provide answers to the following to 3 decimal places.Part a)What is the expected number of policies that will pay out before the insured parties have reached age 61?Part b)What is the variance of the number of policies that will pay out before the insured parties have reached age 61?Part c)What is the probability that at least two policies will pay out before the insured parties have reached age 61?

Let i_t denote the effective annual return achieved on an equity fund achieved between time (t -1) and time t. Annual log-returns on the fund, denoted by In(1 + i_t) , are assumed to form a series of independent and identically distributed Normal random variables with parameters u = 6% and o = 14%.An investor has a liability of £10,000 payable at time 15.

Suppose Y has approximately exponential distribution with mean 8 years. a) Find the probability that a remote control of this type will last more than 15 years. b) Find the probability that of eight such remote controls at least one will last more than 15 years. c) What should the warranty period for these remote controls be if the manufacturer wants 85% of the remote controls to last beyond the warranty period? d) What is the moment generating function of Y .
Everyday, James reverses his car from his driveway on to the road in such a way that there is a very small probability P that his car will be involved in a collision. ( i) Show that the probability that there will be no collision in a five-day week is (1−P)^5 and state one assumption that is made in your answer. (iii) Let P = 0.001. Check that the Poisson approximation can be used, and find the approximate probability that James will avoid a collision in 500 days.
