Ohhh... I get what you mean now. So it was a language barrier. Thanks a lot for a clarification!

HI, thanks for the feedback, my issue with this explanation is, we learn at least 1 dog is M and I agree with the 3 remaining possibilities. However, the question is "What is the probability that the other one is a male?" Not, "what is possibility that both are males", and it also doesn't tell you whether the first one is M or F, since the statement was that at least one is a M. I interpreted it like this: you pick one dog, and must find out what is possibility the other one is a male. I'm not a native speaker. So you interpret the question like "what is possibility that both are males"? Why?

Hey guys, this is actually an old problem solved by vos Savant, and I can't get to the bottom of it. It goes like this: A shopkeeper says she has two new baby beagles to show you, but she doesn't know whether they're male, female, or a pair. You tell her that you want only a male, and she telephones the fellow who's giving them a bath. "Is at least one a male?" she asks him. "Yes!" she informs you with a smile. What is the probability that the other one is a male? Savant replied "one out of three". I convinced myself pretty hard that the answer should be 2/3, so I'm looking for explanation of Savant's answer. If at least one is a male, and you have 2 puppies, one yellow and one green collar, there are 3 possible combinations (I agree with her so far): YM & GM YM & GF YF & GM So, if you choose Y collar, there is 2/3 chances, that the other one is a male, and of course the same for G collar. Where did I get it wrong?
