From the given above, the probability of rolling 2 is 13/72. The probability of rolling 3 is 9/72. We are asked for the probability of rolling 2 OR 3. Since the conjunction OR is used, we add their probabilities. The addition will yield an answer of 11/36. If this is converted to percentage, the answer is approximately 31%.
