Question

13. There are 19 students in an MA 206 class at FCC. How many ways are there to select 5 students for a group project?

Answer 1

We have 19 students in a class.

We have to find how many different groups of 5 students can be selected from that class.

This is a combination of n=19 in r=5 and can be calculated as:

`\begin{gathered} C(n,r)=(n!)/((n-r)!r!) \\ C(19,5)=(19!)/(14!5!)=11628 \end{gathered}`

Answer: there are 11628 possible groups.
