Bob was away last week and did not engage with the contents of the lectures of his modules. This week he is back again but hasn't catched upwith the lectures yet. Let X be the proportion of material that he will understand in this week's Probability lecture, and Y the proportion ofmaterial he will understand in this week's Calculus lecture. The joint probability density function for the two random variables is of the formfxy(x,y) = 1.6 x + 0.4 y, for 0

Here, joint probability distribution is given. And also marginal distribution of x is given Use the…

A bank operates both a drive-up facility and a walk-up window. On a randomly selected day, let X be the proportion of time that the drive-up facility is in use (at least one customer is being served or waiting to be served) and Y be the proportion of time that the walk-up window is in use. The joint PDF is ... fxy (x, y) = 5 (x + y²) • What is the probability that neither window is busy more than one-quarter of the time? • What is f(X)? • What is fy(y)?

A salesman has scheduled two appointments to sell encyclopedias. His first appointment will lead to a sale with probability 0.3, and his second will lead independently to a sale with probability 0.6. Any sale made is equally likely to be either for the deluxe model, which costs $1000, or the standard model, which costs $500. Determine the probability mass function of X, the total dollar value of all sales.
