Let Y1 denote the weight (in tons) of a bulk item stocked by a supplier at the beginning
Chapter 5, Problem 5.38(choose chapter or problem)
Let Y1 denote the weight (in tons) of a bulk item stocked by a supplier at the beginning of a week and suppose that Y1 has a uniform distribution over the interval 0 y1 1. Let Y2 denote the amount (by weight) of this item sold by the supplier during the week and suppose that Y2 has a uniform distribution over the interval 0 y2 y1, where y1 is a specific value of Y1. a Find the joint density function for Y1 and Y2. b If the supplier stocks a half-ton of the item, what is the probability that she sells more than a quarter-ton? c If it is known that the supplier sold a quarter-ton of the item, what is the probability that she had stocked more than a half-ton?
