Respuesta :

Using the combination formula, it is found that 749,398 5-disc combinations can be made from the collection.

The disks are chosen without replacement, hence the combination formula is used to solve this question.

What is the combination formula?

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

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

In this problem, 5 disks are taken from a set of 6 + 10 + 4 + 9 + 12 = 41 disks, hence:

[tex]C_{41,5} = \frac{41!}{5!36!} = 749398[/tex]

749,398 5-disc combinations can be made from the collection.
