You roll two dice. What is the probability that the sum of the dice is even or the sum of the dice is less than 6? Make sure you only account for dice sums that are both even and less than 6 once. Write your answer in the form of a fraction, using the slash ( / ) key. Reduce fractions to their lowest terms.
