Car repairs: Let E be the event that a new car requires engine work under warranty and let T be the event that the car requires transmission work under warranty. Suppose thatP(E)= 0.06, P(T) = 0.09, P(E and T) -0.02. Part 1 out of 2 Find the probability that the car needs work on either the engine, the transmission, or both.

3. A car manufacturer offers a 5yr/Unlimited km warranty on one of its models. Historically, 8% of cars sold will require repairs under the terms of this warranty. Suppose a dealer sells 190 cars of that model and let X be the number of those cars that will require service under the terms of the warranty. (a) A suitable probability model for X is a binomial distribution. What are the parameters of the binomial model in this case. Justify the...

The probability that a certain make of car will need repairs in the first six months is 0.35 . A dealer sells 6 such cars. What is the probability that at least one of them will require repairs in the first six months? Write only a number as your answer. Round your answer to four decimal places (for example: 0.7319). Do not write as a percentage.

Exercise 5(SOA). A car dealership sells 0,1, or 2 cars on any day. When selling a car, the dealer also tries to persuade the customer to buy an extended warranty for the car. Let X denote the number of luxury cars sold in any given day and let y denote the number of extended warranties sold. We have: 1 12 P(X = 0, = 0) = 5; P(X = 1, Y = 0) = 12, P(X = 2, Y =...
A car dealer states that a new brand of car gets 35 miles per gallon on...
A car dealer states that a new brand of car gets 35 miles per gallon on average. Suppose a consumer group claims that these cars get less than 35 miles per gallon. A sample of 40 cars is selected, and the sample mean for the 40 cars is 33 miles per gallon while the sample standard deviation is 3.8. Have the assumptions for this test been met? Why or why not? State the null and alternative hypotheses for this test....

Q: A car dealer sells X cars each day and always tries to sell
an extended warranty on each of these cars. Let Y be the number of
extended warranties sold, then Y >= X. The joint pmf of X and Y
is given by:

Ellise is a car dealer for Tesla’s Model X, which costs on average $100,000 and if he sells a car he receives a 20% commission. However, the probability of the number of cars he sells in a given day follows a Pois(0.6). Assume independence. For all the questions I want to see your code and you output from R. a. Find the probability that he sells more than 2 cars in a given day b. Find the probability that he...
