When rolling a 6-sided die twice, determine P(sum of 5).

The possible pairs that sum to 5 are (1,4), (2,3), (3,2), and (4,1). There are 4 favorable outcomes. The total number of possible outcomes when rolling a 6-sided die twice is 6 * 6 = 36. Therefore, the probability of rolling a sum of 5 is 4/36.
