Determine Probability Distribution

In a certain carnival game a player pays $1 and then tosses a fair coin until either a "head" occurs or he has tossed the coin four times. He receives fifty cents for each toss. Determine the probability distribution for the experiment of playing the game and observing the player's earnings.

Insurance

Please see attached document. If an individual with initial wealth w that is facing a random risk X that takes values è with probability p and value zero with probability 1 - p. If the individual does not take insurance, his wealth will be w - X. If he takes insurance, his wealth will be w - a, where a is the insurance pr

Probability : Proportion Distribution Problem

Airline company officials find that 86% of all people who make reservations show up for their flights. If an airline has accepted 240 reservations and if there are 213 available seats, find the probability that the airline will have a seat for each person who has reserved one and who shows up.

Probabilities : Strong Law of Large Numbers

Please see the attached file for full problem description. Recall that the sequence of random variables defined on the probability space converges near-certainly towards c if and only if converges towards c) = 1. The purpose of this exercise is to prove the following result: Strong law of large numbers: Let

Probabilities : Probability Density and Marginal Density

Please see the attached file for full problem description. --- The random vector (X,Y) has density.... where is the indicating function on that interval, i.e. it is equal to 1 if y belongs to and is equal to 0 otherwise. a. Evaluate c so that g is a probability density. b. Find the marginal densities of X and Y.

Probabilities : Marginals

A bag contains r balls, of which 2 are red and r - 2 are black. We draw a ball at random, we write down its color, and we put it to one side (not back in the bag). We repeat the procedure r times. Let X be the number of draws needed to obtain a red ball, and let Y be the number of draws needed to obtain a second red ball. a. F

Probability : Exponential Density Function

#26 Please see the attached file for full problem description. a) A lamp has two bulbs of a type with an average lifetime of 1000 hours. Assuming that we can model the probbility of failure of these bulbs by an exponential density function with mean mu = 1000. Find the probability that both of the bulbs fail in 1000 hours.

Probability

An octahedron is a three dimensional shape with eight sides that are equilateral triangles. THis shape is used as a die in games such as Dungeons and Dragons because all eight sides come up with equal probability. A. Assuming the sides are numbered 1 through 8, and a person throws two octahedral dice, what are the possible su

Policy Iteration : Probability Distribution and Maximizing Profit

Please see the attached file for the fully formatted problems. 1. A machine in excellent condition earns $100 profit per week, a machine in good condition earns $70 per week, and a machine in poor condition earns $20 per week. At the beginning of any week a machine can be sent out for repairs at a cost of $90. A machine s
