Step-by-step explanation:

Answer 2

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.
