4 12-sided dice are rolled. What is the probability that the number of dice showing a two digit number is equal to 2? Express your answer as a common fraction. (Assume that the numbers on the 12 sides are the numbers from 1 to 12 expressed in decimal.)

D=4; C=2; [((D nCr C * 11^(D-C))  / 12^D] * 3 = 121 / 1152
