Question

18 students are going on a field trip the bus can fit 14 so four of them will have to ride in a car and how many ways can we choose the four students who must ride in the car

Answer 1

Number of ways we can choose the four students who must ride in the car = 3060 ways

Explanation:

This is a combination question.

The number of selections of "r" objects from the given "n" objects is denoted by;

C(n,r), and is given by;

C(n, r) = n!/[r!(n - r)!]

In this question, n = 18 and r = 4

Thus;

C(18, 4) = 18!/[4!(18 - 4)!]

C(18,4) = 3060

Number of ways we can choose the four students who must ride in the car = 3060 ways
