centuries have nothing to do with humanity.....may be I'm wrong but if the issue raises even more India can be criticised on global level I think we should act diplomatically on global level . anyway its jus my view .

totally agreed as we can provide them temporary shelter for the time being and try level hard to take myanmar govt. into confidence with the help of international agencies ,,,, once a life gone, we will never be able to get it back and we need to respect the vision of our forefathers- nehru , indira gandhi ,that india has the capability to lead the region - economically , politically and morally as well and forward the same message to our next generation :)

Humanitarian stand doesn't creates any extra resources to accommodate 40k rohingyas and we cannot compromise with our internal demographic dividend...Humanitarian perspective is a good thing but it cannot be done at a cost of our own limited resources
sir methods of differentiation

Good Evening Sir, I have watched the full probability course of yours and it was very helpful. I have one doubt Sir . Q. V Anand and Gary paly a series of 5 chess games. The probability that V Anand wins a game is 2/5 and the probability of Gary winning is 3/5.There is no probability of a draw. The series will be won by the person who wins 3 matches.Find the probability that Anand wins the series (The series end the moment when any of the two win three matches.) Options:- a. 992/3125 b.273/625 c.1021/3125 d.1081/3125 Is there any short way of doing this question?
