Sam is the captain of an academic team in the class. A teacher will choose 6 of the 25 students in the class to be on an academic team. How many ways can 6 students be chosen as a team from this class given that Sam must be one of those students?

Respuesta :

Answer:

42,504 ways to choose a team.

Step-by-step explanation:

The order in which the students are selected is not important. So we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

Sam

And 5 students from the remaining 24.

Then

[tex]C_{24,5} = \frac{24!}{5!(24-5)!} = 42504[/tex]

42,504 ways to choose a team.
