Sad.
It would be a lot more exciting if it were not total nonsense (Sorry, but you did ask for our thoughts, and that's what they are). This... -
bob012345 replied to the thread B Geometry Puzzle with 20 points in a cross pattern.If I remember, that was so two weeks ago, probably what I meant by the permutations, was the relative rotations of the squares with...

bob012345 replied to the thread B A Little Probability Puzzle.Thanks all! I originally came up with this while pulling identical pairs of socks out of my dryer. What are the odds? If I do laundry...

You are right. ## 1-(1-P(B_5))^m=0,9 ## ## m=\ln(0,1)/\ln(1-P(B_5))\approx2175 ## where ## P(B_5)=1/(9\cdot7\cdot5\cdot3\cdot1) ## is...

bob012345 replied to the thread B A Little Probability Puzzle.So the answer to my first question in the OP (the probability of having at least one of the original pairings) can be answered by using...
-
No! It's not a typo.
-
That last answer is not right. The correct answer is 2175. Also, does your formula give p(4)=0?
-
Without loss of generality, we can assume that the first set of pairings is (1,2), (3,4) ... (9,10). The number of ways of getting...
