"Craps" in the game refers to rolling a 2, 3, or 12 on the come-out roll. There is 1 way to roll a 2: (1,1). There are 2 ways to roll a 3: (1,2) and (2,1). There is 1 way to roll a 12: (6,6). So, there are 4 ways to roll craps. For an even sum: There are 2 ways to roll a 4: (1,3), (3,1), (2,2). There are 3 ways to roll a 6: (1,5), (5,1), (2,4), (4,2), (3,3). There are 3 ways to roll an 8: (2,6), (6,2), (3,5), (5,3), (4,4). There are 2 ways to roll a 10: (4,6), (6,4), (5,5). So, there are 10 ways to roll an even sum. Combining the two, there are 14 ways to roll either craps or an even sum. Given 36 possible rolls, the probability is 14/36 or 7/18. Note: These calculations are based on the assumption that each of the 36 possible rolls of two dice is equally likely.
