A building contractor requires a roll of roofing felt. There are threesuppliers in the area and the probabilities (based on his previousexperiences and the location of the suppliers) that the contractor willinstruct his vanman to visit a particular supplier are:A: the vanman goes to supplier A, P[A] = 0.6B: the vanman goes to supplier B, P[B] = 0.2C: the vanman goes to supplier C, P[C] = 0.2Each supplier stocks roofing felt produced by two manufacturers, X andY. Both types of roofing felt sell at the same price and both satisfy thecurrent building regulations. The stock situation at each of the suppliersis:SupplierABCNo. of 'X' rolls103030No. of 'Y' rolls302010The vanman will be told by his employer which supplier to visit.Which roll type is the vanman most likely to return with?

A person must pay $$6 to play a certain game at the casino. Each player has a probability of 0.16 of winning $$12, for a net gain of $$6 (the net gain is the amount won 12 minus the cost of playing 6).Each player has a probability of 0.84 of losing the game, for a net loss of $$6 (the net loss is simply the cost of playing since nothing else is lost).What is the Expected Value for the player (that is, the mean of the probabiltiy distribution)? If the Expected Value is negative, be sure to include the "-" sign with the answer. Express the answer with two decimal places.

Given two events G and H, the probabilities of each occurring are as follows: P(G) = 0.35; P(H) = 0.19; P(H AND G) = 0.1. Using this information: Find the complement of P (H AND G). Type answer with 0 in front of decimal to 2 places. If answer is like .2, type 0.2 not .2 or 0.20.
Suppose E= "sum is 5" and F= "exactly one of the dice is even". Are E and F independent? Explain why or why not.
A gasoline manufacturer has two big projects worldwide, one is in Southeast Asia and the other one is along Africa. The probability of the project in Southeast Asia being successful is 40% and that of the project in Africa is 70%. Suppose that the success of the two projects are independent of each other, find the probability that only the Southeast Asian project succeed given that at least one of the two projects is successful. Select the correct response: 30% none of these 80% 45% 15%
Answers must be in 4 decimals 1. Bulsu plans to enforce speed limits using radar traps at 4 different locations within the campus. The radar traps at each of the locations L1, L2, L3, and L4 are operated 40%, 30%, 30%, and 20% of the time, and a person who is speeding on his way to work has probabilities of 0.2, 0.1, 0.5, and 0.2, respectively, of passing through these locations. If the person received a speeding ticket on his way to work, what is the probability that he passed through the radar trap located at L2? 2.

Suppose I flip a fair coin n = 20 times. A psychic tries to predict the outcome before each flip. Three researchers have different ideas about the psychic's ability. There is Sydney, the Skeptic (S), who thinks the psychic's success rate is between 49% and 51%. There is Morgan, the Mark, M, who thinks that the psychic's success rate is 80%. And there is Carter, the Cynic (C), who thinks the psychic's success rate is 10%. Specifically: S+ 0 ~ U(.49, .51) M + 0 = .80 C0 = .10 %3D In all cases, assume the number of successful predictions follows a binomial distribution with success rate 0. Usek for the number of successes and n for the number of trials. Given all that: Determine the formula for the Bayes factor (a.k.a., likelihood ratio) supporting Carter over Morgan. Call that Bayes factor Bc:M Determine the formula for the Bayes factor (a.k.a., likelihood ratio) supporting Morgan over Sydney.

Your car is making a funny noise. You believe that the problem is either with the wheel or the axle, and you believe the probability is 0.3 that the wheel needs to be replaced, and 0.7 that the axle needs to be replaced. You need to decide whether to replace the wheel or the axle first. The cost of each alternative is given in the following table (if you decided to replace the wrong part first, you have to replace both of them). The Wheel is broken p = 0.3 The Axle is broken p = 0.7 Replace Wheel First Replace Axle First 600 1500 1500 900 a) Find the EV of each decision alternative. Which part should you replace first? b) What is the EVPI?
In gambling, the chances of winning are often written in terms of odds rather than probabilities. The odds of winning is the ratio of the number of successful outcomes to the number of unsuccessful outcomes. The odds of losing is the ratio of the number of unsuccessful outcomes to the number of successful outcomes. For example, if the number of successful outcomes is 2 and the number of unsuccessful outcomes is 3, the odds of winning are 2:3 (read "2 to 3") or 2 2 (Note: If the odds of winning are the probability of success is 3' 5.) 2 3 The odds of an event occurring are 3:1. Find (a) the probability that the event will occur and (b) the probability that the event will not occur.
You purchase a brand new car for $15,000 and insure it. The policy pays 78% of the car's value if there is an issue with the engine or 30% of the car's value if there is an issue with the speaker system. The probability of an issue with the engine is 0.009, and the probability there is an issue with the speaker system is 0.02. The premium for the policy is p. Let X be the insurance company's net gain from this policy. (a) Create a probability distribution for X, using p to represent the premium on the policy. Enter the possible values of X in ascending order from left to right. P(X) (b) Compute the minimum amount the insurance company will charge for this policy. Round your answer to the nearest cent
