Answer:

0.7703

Explanation:

The easiest way to calculate this is to find the probability that none of the cubes show a 2. The probability that a cube doesn't show a 2 is 11/12.


(11)/(12) * (11)/(12) * (11)/(12) = 0.7703. Now we have to subtract this value from one which gives us 0.2297. Hope this helps
