Lila Decker · Answer 1

The number of ways of picking up a red cube out of 12 cubes are 5/12. Number of ways of picking up a second red cube is 4/11.

Thus probability of picking up 2 red cubes = 5/12 * 4/11 = 20/121.

20 / 121 =.165 or. 17

So the probability of Celinda getting two red cubes is. 17.
