Answer:

1/12

Step-by-step explanation:

Let’s list out cases:

1+1:

Probability of getting 1 and 1 is (1/6)^2 = 1/36

1+2:

Probabilty of getting 1 and 2 is (1/6)^2 = 1/36 and getting 2 and 1 is (1/6)^2 = 1/36.

That is all of the cases because 1+3 and 2+2 are equal to 4. Summing it up, we get: 3(1/36) = 1/12
