Answer:
15
Step-by-step explanation:
There is a special function for this kind of problem it is the choose function and this problem asks
6 choose 2
the way to do this is
[tex]\frac{6*5}{2!}[/tex]
The way to think about this is imagine two slots
The first slot has 6 options to choose from so we write
6
The second slot has five options as the one person has already been chosen
6 5
6*5=30
divide by two for the repetitions
and we have 15
