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: value of x 2 3 4 5 6 7 8 probability 1/16 2/16 3/16 4/16 3/16 2/16 1/16 p(x < 5) has value:
