The reason is that P (A)+P (B) P ( A) + P ( B) double counts outcomes where A A and B B both happen. For example, suppose A A is “⚅ on 1st roll” and B B is “⚅ on 2nd roll”. Then, it is not hard to see that the event A or B A or B happens on 11 out of 36 outcomes, so P (A or B) = 11 36 ≠ 12 36 = 1 6 + 1 6 = P (A) +P (B).
