Answer:
2/5
1/6
1/10
Step-by-step explanation:
total number of cubes = 12 + 5 + 3 = 20
Probability of picking green cubes = total number of green cubes / total number of cubes = 12/30 = 2/5
Probability of picking blue cubes = total number of blue cubes / total number of cubes = 5/30 = 1/6
Probability of picking yellow cubes = total number of yellow cubes / total number of cubes = 3/30 = 1/10
