probability, drawing cards from a deckI got a wierd problem today I wasn't sure how to solve. It seems to be a wierd combination of probability and permutations. (or combinations) A logarithm is just a misspelled algorithm. #3 20050901 04:50:03

Re: probability, drawing cards from a deckI would be interested in knowing how to solve this directly, however, without iterating the possibilities and choosing the igloo myrtilles fourmis #5 20060317 06:53:25
Re: probability, drawing cards from a deckHow many different ways can you select 3 cards from 52? 52 choose 3. Or (52 * 51 * 50) / (3 * 2 * 1). That's equal to 22100. #6 20060317 13:33:56
Re: probability, drawing cards from a deck
Great! The ways how 3 is chosen from 52 have the same probability. That's the meaning of Classical Probility Model. The next thing is to select ways to meet the question, no matter how them are generated. Looking at the problem from a different angle is often where innovations come from! X'(yXβ)=0
