Answer:
It isn't much help, but the answer is NOT C. 6
I just took the test and C was not the answer !! I will update this if I figure out what it was.
Since the order of selection does not matter, we will use combinations to solve this problem.
We are to form the combination of 30 objects taken 6 at a time. This can be expressed as 30C6.
This means the six teachers can be selected in 593775 ways.
So the correct answer is option A
