P=8.3\%

1) Let's enlist the possible outcomes of two dices:

(1,1) (1,2), (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

There is a total of 36 outcomes

2) Let's bold the favorable outcome, either the sum of the cubes is 11 or 2:

(1,1) (1,2), (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

So there is a total of 3 favorable outcomes:

3) So let's write it as a Probability:


P=(3)/(36)=(1)/(12)=0.083

This can also be written as a percentage multiplying by 100. Hence, the answer is 8.3%
