The values p and q in the quadratic expression 2x² - px + q are determined by throwing two standard fair cubical dice, one red and one blue.

p is given by the value shown by the red die and q is given by the value shown on the blue die.

What is the probability that the equation 2x² - px + q = 0 will have a solution that is a prime number?

 Prob = 1/18=0.0555....
