How many ways can a supermarket chain select 4 out of 12 possible sites for construction of new supermarkets?​

Answer 1

6

Explanation:

Answer 2

I am pretty sure it's 495

Explanation:

The context of this problem makes me think that the order in which the sites are in does not matter

if that's the case we can solve this using combinations

the combinations formula is as follows:

ACB=
`(A!)/((A-B)!*B!)`

so 12C4=
`(12!)/((12-4)!*4!)=495`
