From a group of 8 people 5 will each win $1000. How many different winning groups are possible?

6720 ways different

Step-by-step explanation:

In this case, we must calculate the different ways using the permutation formula:

nPr = n! / (n - r) !

where n is the total number of people and r would come being the group of person that you want to put together the groups, therefore n = 8 and r = 5

replacing:

8P5 = 8! / (8 - 5) !

8P5 = 6720

That is to say that there are 6720 ways different winning groups are possible
