How to solve joint probability
WebThere is probably a simpler or more computationally efficient way, but this solution is fast enough for what you may be trying to do. First, we input the pdf of x and y. pdfxy <- function (x, y) (x^2 * y + x * y^2)/2. We convert this to a pdf of just y … WebFirst we identify the part L of the plane where the joint density function of X and Y "lives." Draw the vertical lines x = 1 and x = 2. Draw the line y = x. The joint density lives on the part L of the first quadrant that is between x = 1 and x = 2, and below y = x. This region L is a trapezoid with corners ( 1, 0), ( 2, 0), ( 2, 2), and ( 1, 1).
