Suppose we roll two fair four-sided dice. Let X denote the sum of the two roll outcomes. For example, if the first roll yields 3 and the second roll yields 1, then X = 3 + 1 = 4. The probability distribution for X is given below. The probability of rolling a pair of 4s is:
A)1/16.
B)1/8.
C)3/16.
D)13/16.
