Computation of probability of events using permutations and combinations

Permutations and combinations are two fundamental concepts in probability theory and statistics. They are used to calculate the probability of certain events. A permutation is an arrangement of objects in a particular order, while a combination is a selection of objects without regard to their order. To compute the probability of an event using permutations…

Permutations and combinations

Permutations and combinations are concepts in combinatorics, which is the branch of mathematics concerned with counting and arranging objects. A permutation is an arrangement of objects in a specific order. The number of permutations of n objects taken r at a time, denoted by P(n,r), is given by: P(n,r) = n!/(n-r)! where n! represents n…
