Let X denote the number of Canon digital cameras sold during a particular week by a certain store. The pmf of X is as follows x 01 2 3 4 Px(x) 0.1 0.2 0.3 0.16 0.24 The probability that a particular customer buys an extended warranty given they purchase a camera is 0.60. Let Y denote the number of purchasers during this week who buy an extended warranty. (Give answers accurate to 3 decimal places.) (a) What is P(X-4, Y- 2)?
(b) Determine the joint pmf of X and Y.
(c) Determine the marginal pmf of Y P(y)
(d) Calculate P(X Y)
