What is the probability of rolling 2 standard dice which sum to 5?Note: enter your answer in the form "5/7"

To find the probability of rolling 2 standard dice which sum to 5, we first need to determine the total number of outcomes when rolling 2 dice. A standard die has 6 faces, so when rolling 2 dice, there are 6*6 = 36 possible outcomes.

Next, we need to find out how many of these outcomes result in a sum of 5. The pairs that sum to 5 are: (1,4), (2,3), (3,2), (4,1). So there are 4 outcomes that result in a sum of 5.

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes. So, the probability of rolling a sum of 5 with 2 dice is 4/36 = 1/9.
