The probability that the sum of the numbers rolled is either even or a multiple of 5 is 11/18.

With one roll of three dice, the probability is 7/8.

The addition rule of probability states that the probability that one or the other will happen is the probability of one plus the probability of the other. This rule only applies to mutually exclusive events. For example, the probability that a dice roll will be a 3 is 1/6. The probability that the dice roll will be even is 1/2. These are mutually exclusive events as the dice cannot be both 3 and even. Thus the probability of the dice roll coming up either a 3, or even, is 1/2 + 1/6 = 2/3.

There are only three even numbers on a "legal" six sided dice (2,4 & 6), which ever dice is designated as "first" whether rolled independently or in unison will have a 1 in 2 chance of being even. Put another way: legal dice, designate first, 3 even, 3 odd, 50/50. Bonus Answer: Applies to second dice also.

The probability of getting an even number on a six sided dice is 3 out of 6 or one half because the only even numbers are 2,4,6 (which are all even).
