Question

What is the probability that the sum of the numbers that came up on the two dice is seven, given that at least one 6 came up

Answer 1

`\displaystyle\\Answer:P(A)=(1)/(6).`

Explanation:

If one of the dice has a 6, then the other dice should have a 1 (7-6=1).

A dice has six faces and each face has a different number from 1 to 6.

Consequently, the probability that on a dice the digit 1 will fall is equal:

`\displaystyle\\P(A)=(1)/(6).`

This is the solution to the problem.
