18.   The number of outcomes with a sum of 6 is 5.   We need to subtract the outcomes that have both an even number on the first die and a sum of 6 because we have counted those outcomes twice. This number of outcomes is 2.   The number of outcomes with either an even number on the first die or a sum of 6 is  18+5-2=

21.   The probability is 21/36=7/12.   The answer is 7/12.
