Answer:
Number of ways we can choose the four students who must ride in the car = 3060 ways
Step-by-step 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
