4. Suppose you roll two fair (six-sided) dice simultaneously. Let X denote the random variablethat is the minimum of the two rolled numbers, and let Y denote the random variable thatis the maximum of the two rolled numbers.(a) State the joint probability mass function (pmf) of X and Y.(b) Using the joint pmf, find P(2 ≤X ≤ 4, 3

Given that two dice are rolled simultaneously then sample space will be,

(b) Test two independent circuits one after the other. On each test, the possible outcome is either overvoltage (0) or undervoltage (U). Assume that all circuits are overvoltage with probability 0.4. Let X be the number of overvoltage circuit in the first test and Y be the number of overvoltage circuit before you observed undervoltage. If both circuit is overvoltage or undervoltage, Y = 2. Find the joint PMF of X and Y.
