Order of choosing the two doesn't matter, because picking 
John first and Suzy second is the same as picking Suzy first 
and John second.  So this is the combinations of 6 things
taken 2 at a time.

C(6,2) = 15

That's 6 nCr 2 on the TI-83 or 84 calculators.

Press ON
Press CLEAR
Press 6
Press MATH
Press the left arrow key once
Press 3
Press ENTER

You will see:

6 nCr 2         
               15
