Answer:
No of red balls = 5
No of green balls = 4
No of blue balls = 3
Total no of balls = 12
a) Probability of getting blue ball = No of blue balls/Total no of balls
Probability = 3/12 = 1/4
b) Probability of not getting green ball = No of red balls + No of blue balls / Total no of balls
Probability = 5 + 3 / 12
Probability = 8 / 12 = 2/3
c) Probability of getting a red ball = No of red balls/Total no of balls
Probability = 5/12
Hope it helps you!!
