Probability of permutation

Webb18 jan. 2016 · Probability theory is an interesting area of statistics concerned with the odds or chances of an event happening in a trial, e.g., getting a six when a dice is thrown or drawing an ace of hearts from a pack of cards. To work out odds, we also need to have an understanding of permutations and combinations. WebbProbability and permutations and combinations are very much interlinked and are useful every where.

So the probability of particular tuple of j values which defines a unique WebbIn Mathematics, the concept called “permutation and combinations” are applied in probability, relations and functions, set theory and so on. What is the factorial formula?
