Answer:
Is this even possible
Step-by-step explanation:
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.
![30C6= \frac{30!}{6!*24!} \\ \\ = 593775](https://tex.z-dn.net/?f=30C6%3D%20%5Cfrac%7B30%21%7D%7B6%21%2A24%21%7D%20%20%5C%5C%20%20%5C%5C%20%0A%3D%20593775%20)
This means the six teachers can be selected in 593775 ways.
So the correct answer is option A
