1 AnswerMathematics1 decade agoProbability/ permutation question.?
If an ordered set of n unique items is randomized, what is the probability of at least one item will end up in the same place it was before randomization?
I know the answer is close to 60% that at least one will, but I don't know how to derive the answer or an expression for the probability.
5 AnswersMathematics1 decade agoWhat is the probability of any item matching with two sets of items with different, random ordering?
A match would be any one of the same item in each set ending up in the same position. For instance, if two decks of shuffled cards are laid out in pairs, one card from each deck, what are the chances that at least one pair will be of identical cards?
I am more interested in how to solve the general problem than a specific answer. Simple combinatorics doesn't seem to do it. It seems to be devilishly recursive.
