Suppose that 5 out of 13 people are to be chosen to go on a mission trip. in how many ways can these 5 be chosen if the order in which they are chosen is not important.

5 People can be chosen  in 1287 ways if the order in which they are chosen is not important.

Step-by-step explanation:

Given:

Total number of students= 13

Number of Students to be selected= 5

To Find :

The number of ways in which the 5 people can be selected=?

Solution:

Let us use the permutation and combination to solve this problem

So here , n =13  and r=5 ,  

So after putting the value  of n and r , the equation will be
