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
