Hi there,

Let E1 and E2 respectively denote the events that a red ball is transferred from a bag 1 to 2 and a green ball is transferred from bag 1 to bag 2

P(E1)=4/6

P(E2)=2/6

LET A be the event that the ball drawn is green

(i) when a red ball is transferred from bag 1 to 2

P(A/E1)=5/9

2) when a green ball is transferred from bag 1 to 2

P(A/E2)=6/9

P(E2)/A= p(E2) p(A/E2)/ p(E1) p(A/E1) + p(E2)p(A/E2)

=3/8

Hope it helps you

Good luck!

Hello Gautam,

Let us consider A1 is the events that a red ball is transferred from a bag I to Bag II and  A2 Event is that green ball is transferred from the bag I to Bag II.

P(A1) = 4/6 & P(A2) = 2/6

Assume B be the event that the ball drawn from Bag is Green.

(1) when a Green ball is transferred.

P(B/A1) = 6/9

(2) when a Red ball is transferred.

P(B/A2) = 5/9

Now, P(A2/B) = [P(B/A2) × P(A2)] ÷ [(P(A1) × P(B/A2)) + (P(A2) × P(B/A1)]

Similarly, P(A2/B) = [((2/6) × (6/9)) ÷ ((4/6) × (5/9)) + ((2/6) × (6/9))]

= 3/8

Probability that the ball drawn fromBag I to Bag II is 3/8.

Hope this information was useful to you.

Good Luck!!

Hlo sir, this is Sourav S. Bag from Odisha. In JEE MAINS (Crl- 6,71,289 : Sc- 61,252) i got this. In OJEE (Gen- 942 : Sc-123). So according to it, with which Rank card i should participate in B.tech Counciling to expect a seat in Govt. College with a good branch.

divya 8th Oct, 2021

Hello Sourav,

I would suggest you to use your OJEE rank card as you do have a better ranking there and being from Orrisa you have good chances of getting government colleges there. The colleges you have good chances of getting are:

  • College of Engineering and Technology, Biju Patnaik University of Technology
  • VSSUT - Veer Surendra Sai University of Technology
  • Parala Maharaja Engineering College
  • Government College of Engineering
  • Central Institute of Plastics Engineering and Technology

Good luck, Hope it helps!!

Manas Daspriya 8th Oct, 2021

Hello aspirant,

Hope you are fine and healthy.

As your JEE Mains rank for SC category is 61252 which is not very promising.

I would suggest that you should go with OJEE SC rank 123 which is quite impressive and have a chance to get government institutions.

Here is a list of colleges where you can try for admission,

=> Institute of Management and Information Technology, Cuttack

=> Government College of Engineering, Kalahandi

=> Government College of Engineering, Keonjhar

=> Parala Maharaja Engineering College, Behampur

Here is a link, where you can get more information regarding engineering colleges which take admission through OJEE counselling,
