18.   The number of outcomes with a sum of 10 is 3.   We need to subtract the outcomes that have both an even number on the first die and a sum of 10 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 10 is  18+3-2=

19.   The probability is 19/36.   The answer is 19/36.
