Answer:

1/6

Step-by-step explanation:

We can make a Punnett square to find number of favourable outcome

so

            cube1

         +

cube2    1          2          3        4          5         6

1            2         3           4        5          6        7

6           7           8          9         10        11         12

The probability of rolling doubles given that the sum is 6

<h3> favourable outcome / number of outcome</h3>

 6 / 36

  1 / 6
