2. Assume two fair dice are rolled. Let X be the number showing on the first die and number showing on the second die. (a) Construct the matrix showing the joint probability mass function of the pair X,Y. (b) The pairs inside the matrix corresponding to a fixed value of X - Y form a straight line of entries inside the matrix. Draw those lines and use them to construct the probability mass function of the random variable X-Y- make...

please answer the following clearly and make sure it is
correct
6. You are in possession of a pair of 4-sided fair dice (green and red). If you roll any individual die, the possible results are 1, 2, 3, or 4, each equally likely. Let Ai be the random result on the green die, and A2 be the random result on the red die. We define the random variable A = A1 A2 the absolute value of difference between the...

Two identical fair 6-sided dice are rolled simultaneously. Each die that shows a number less than or equal to 4 is rolled once again. Let X be the number of dice that show a number less than or equal to 4 on the first roll, and let Y be the total number of dice that show a number greater than 4 at the end. (a) Find the joint PMF of X and Y . (Show your final answer in a...
