The probability that something will not happen is 1 minus the probability that it will happen. Start by calculating the probability that two dice will sum to 4: there are 3 possible ways for this to happen: a 1 on the first die and a 3 on the second, a 3 on the first die and a 1 on the second, or two 2s.

There are 6 x 6 = 36 total possible outcomes for two six-sided dice, so the probability of getting a 4 is 3/36 = 1/12. Therefore, the probability of NOT getting a 4 is 1− (1/12) =11/12. Choice (C) is correct.
