A computer store sells 3 computer models priced at P26,000, 32,000, and 42,000, and two brands of monitors priced at P3,200 and 3, 800, respectively. The joint pmf of X, the computer price, and Y , the monitor price, is given in the table below. X\Y 3,200 3,800 26,000 0.30 0.25 32,000 0.20 0.10 42,000 0.10 0.05 Find the joint probability F(x, y) = P(X ≤ 32,000, Y ≤3,800 ). Compute the marginal probability functions (pmf’s). Describe the events A= { X + Y ≥ 32,800} and find its probability.
