I roll a fair dice 7 times. What is the probability that all the six sides of the dice come up? How should I calculate this?

Why to the power of 7? It doesn't matter what the last throw will appear to be what value because as long as all 6 sides have shown up?

6! / 6^6 * 1 = 720/46656 = 5/324 i'm not good at probability

I see. I wondered because there are 7 throws and it seems like it could permutate to have higher chances?
