Using, permutation and combination, the number of ways in which 10 people can be seated in a row, if there are no restrictions on the seating arrangement is 36,28,800, and if elaine and jerry must sit together is 7,25,760.
<h3><u>
What is permutation and combination?</u></h3>
- Combination and permutation are two alternative strategies in mathematics to divide up a collection of components into subsets.
- The subset's components can be listed in any order when combined.
- The components of the subset are listed in a permutation in a certain order.
- There are only a finite number of permutations and combinations for each data set.
- They can therefore be used to calculate the probability of complex events.
- The number of possible permutations increases and the likelihood that a particular permutation will occur decreases as a set's elements increase.
The number of ways in which 10 people can be seated in a row without any restriction is 10! = 36,28,800.
