Question: 1 / 400

What is the probability of rolling a sum of 7 with two six-sided dice?

1/6

To determine the probability of rolling a sum of 7 with two six-sided dice, we begin by identifying all the possible outcomes when rolling two dice. Each die has 6 faces, resulting in a total of 6 x 6 = 36 possible outcomes.

Next, we need to find all the combinations that result in a sum of 7. The pairs that yield this sum are:

1. (1, 6)

2. (2, 5)

3. (3, 4)

4. (4, 3)

5. (5, 2)

6. (6, 1)

There are 6 successful outcomes that produce a sum of 7. To find the probability, we divide the number of successful outcomes by the total number of possible outcomes:

Probability of rolling a sum of 7 = Number of successful outcomes / Total outcomes = 6 / 36 = 1 / 6.

Thus, the correct answer is 1/6, as it accurately reflects the ratio of favorable outcomes to the total number of outcomes when rolling two six-sided dice.
