There will be 3 cases.
Case 1 : Ball is chosen from 1st bag.
Probability of green ball from 1st bag = (1/3)Γ(2/6)
= 1/9
Case 2 : Ball is chosen from 2nd bag.
Probability of green ball from 2nd bag = (1/3)Γ(5/9)
= 5/27
Case 3 : Ball is chosen from 3rd bag.
Probability of green ball from 3rd bag
= (1/3)Γ(3/9)
= 1/9
So required probability
= 1/9 + 5/27 + 1/9
= 11/27

Hi everyone, we were getting queries specially from 3rd and 4rth year students to get more and more questions and that their college syllabus is different and most of the topics were not taught properly in their college. So, we have designed a Sectional Test series, where tests of CORE subjects will be conducted syllabus wise in Parts.
Syllabus wise Part of Core subjects will be posted in online portal soon.
BEP test series is different than RMS test series, it will have more sectional tests like 4 tests in Drilling, 4 Reservoir and 4 in Production with all other subjects of Petroleum Engineering.
Its built specifically, keeping in mind 3rd and 4rth year Petroleum graduates who wants to build good foundation in Petroleum Engineering.
