Answer 2

Answer:

Hello

Step-by-step explanation:

Total number of balls = 4+5+6 = 15

If 3 balls are drawn randomly and probability that it contains exactly 2 green balls

P(E) = No. of favourable outcomes / Total number of outcomes

P(E) = 3/15

Probability of exactly two green balls ,

P(E) = 2/12...........How

We had taken 3 balls 15-3 = 12
