6. Suppose that we roll a pair of balanced dice. Let X be the number of dice that show 1 and Y be the number of dice that show either 4, 5, or 6. (a) Draw a diagram like Figure 3.1 on page 62 showing the values of the pair (X, Y) associated with each of the 36 equally likely points of the sample space. (b) Construct a table showing the values of the joint...

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...

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...
