Answer:
(B) 2/3
Step-by-step explanation:
Probability = (No. of favourable outcomes)/(Total no. of outcomes)
No. of favourable outcomes = white + green balls = 3 + 3 = 6
Total number of outcomes = white + red + green balls = 3 + 3 + 3 = 9
Probability = 6/9 = 2/3
Hence, the probability that the ball drawn is NOT red, is 2/3.
