In Muscat city, there are two types of services at a gas station. The gas station has a single regular lead-free pump with two hoses. In this context, A indicates the number of hoses being utilized on the self-service station at a certain time and B indicates the number of hoses on the full-service station utilizes at that time. The joint pmf of A and Bie., f(A,B) is shown below. 0.14 0.02 0.05 0.29 0.10 0.13 0. 0.09 0.05 0.13 d. Compute the marginal pmf of A and of B. Using PA(A), what is P(A<=1)? e. Are A and B independent events? Explain.

Lennard is deciding whether to purchase a wireless speaker from a major online retailer. He looks at the reviews for the speaker and notices that out of 100 reviews posted (with possible range of 1−5 stars), 99 reviews are 4 or 5 stars and only 1 review is 1 star-rated. He does, however, notice that the 1 star-rated review was posted very recently - just over the past few weeks. Nevertheless, the average overall rating for the product is 4.7 and Lennard decides to purchase the speaker. Why is the average review statistic misleading in this case?

A chemical manufacturer wants to lease a fleet of 24 railroad tank cars with a combined carrying capacity of 420,000 gallons. Tank cars with three different carrying capacities are available: 7,000 gallons, 14,000 gallons, and 28,000 gallons. How many of each type of tank car should be leased? Let x, be the number of cars with a 7,000 gallon capacity, x₂ be the number of cars with a 14,000 gallon capacity, and x3 be the number of cars with a 28,000 gallon capacity. Select the correct choice below and fill in the answer boxes within your choice. O A. The unique solution is x₁ = X₂ , and x3 = (Simplify your answers.) O B.
