akshayxyz Posted October 27, 2011 Posted October 27, 2011 You might have seen this before, but still worth a revisit. See, whether you can get it without googling.
yoda Posted October 27, 2011 Posted October 27, 2011 it's weird but let me try: choose qn at random indicates 25% prob, since that is listed twice, doubles chances to 50%, since that is listed once, chance of that is 25%, since that is listed twice, doubles chances to 50%, ...
Mariyam Posted October 27, 2011 Posted October 27, 2011 I though probability can only be between 0 and 1?
akshayxyz Posted October 27, 2011 Author Posted October 27, 2011 I though probability can only be between 0 and 1? yes and that can also be expressed in 0-100% (i.e. per 100).
Sachinism Posted October 27, 2011 Posted October 27, 2011 What question? How can you know the probability of being correct, when you don't know the correct answer?
nikred Posted October 27, 2011 Posted October 27, 2011 Damn these filters in my office. I am not able to see the image. :((
Yoda-esque Posted October 27, 2011 Posted October 27, 2011 Depends on the event..since theres no clear event , there's no clear answer.
Vijay.Sharma Posted October 28, 2011 Posted October 28, 2011 Agree with Yods. But to humor the questioner the answer is "d" assuming there is only one correct answer. If there is only one correct answer then the probability you can choose the right one, randomly in one shot, is 1/4 = 25%
The Outsider Posted October 28, 2011 Posted October 28, 2011 This is related to some mathematical paradox, is it?
CasualVisitor Posted October 28, 2011 Posted October 28, 2011 What question? How can you know the probability of being correct, when you don't know the correct answer? +1. My very first thought, when I read this problem.
