There are 2 scenarios. Eithe...Retarded as fuck ...<br /><br />There are 2 scenarios. Either is the faulty coin or not.<br /><br />Result 1/2. Noone is asking you for all the possibilities.<br />Its said that the coin is allready on his tail up.<br /><br />Im a little bit worried that you are doing something important in life...<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-60923183449855611002014-01-31T02:35:19.635+05:302014-01-31T02:35:19.635+05:30THE CHANCES ARE 50%THE CHANCES ARE 50%Anonymoushttps://www.blogger.com/profile/16017574038578720367noreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-72862380475798887342013-10-31T16:14:45.514+05:302013-10-31T16:14:45.514+05:301/41/4Anonymoushttps://www.blogger.com/profile/00280471031464016435noreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-23343387054496293962013-10-22T07:54:52.878+05:302013-10-22T07:54:52.878+05:30Total bullshit, you failed maths I can tell:

Your cases 1, 2 and 3 are NOT possible given the parameters of the question and the constraints of the scenario.<br /><br />There are only two possibilities for the remaining coin: that it is heads or that is has tails. Therefore there is a 1 in 2 chance that the other side is Tails. In other words, a 50% probability since probabilities are expressed as percentages. <br /><br />Gee people, I am glad you are not working on anything important in Life, or maybe you are and that is why the planet is in trouble. Some of the people making these questions and answers up are absolute idiots.

Since the probability of choosing the good coin is 1/2, given that tails is facing up, the probability of heads facing down would be 1/2*1/2 = 1/4.<br /><br />However, the probability of choosing a bad coin is 1/2, which means that the probability of tails facing downwards is 1/2. This is because no matter which tails is facing up, the other tails is facing down too.<br /><br />1-1/2-1/4=1/4. This 1/4 represents tails facing down and heads facing up. But this probability can be ignored in the context of the question because we know that tails and not heads is facing up.<br /><br />Given that tails is facing upwards, the probability of tails facing downwards would be (1/2) / (1/2+1/4) = 2/3Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2893315201359920156.post-67538347497123638292013-08-25T02:32:21.752+05:302013-08-25T02:32:21.752+05:30Hi...
