The number of way to select people from a total of a people is a! /b!·(a-b)!
plugging in 15 for A and 6 for B
P= 15! / 6!(15-6)!
P= 1307674368000 / 720·9!
P= 1307674368000 / 362880
P= 360360
By choosing some items from a set and creating subsets, permutation and combination are two approaches to represent a group of objects. It outlines the numerous configurations for a particular set of data. Permutations are the selection of data or objects from a set, whereas combinations are the order in which they are represented. Both ideas are critical to mathematics.
Here, the differences between permutation and combination are described in detail. Here, we'll talk about both subjects with formulas, examples from everyday life, and questions that have been answered. Students can also work on the Permutation and Combination Worksheet to improve their understanding of this subject and learn shortcuts for answering additional questions.
