Bayes Formula P(A | B) = P(B | A) ⋅ P(A) / P(B)

What is the probability of rolling the sum of 2?

Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.

What is the probability of getting a sum of 7 when rolling two dice?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.

What is the probability of rolling a sum of 6 on a six sided dice?

Answer: The probability of rolling a sum of 6 with two dice is 5/36.
