What is the chance of a Pokemon not getting paralyzed for 12 turns?

Question

In an Gen 8 AG battle, I used Thunder Wave on the opponent's Dusk Mane, and it didn't Paralyze once! What is the chance of this happening?

Thanks both of you. Now I am really convinced I have a bad rng curse.

Answer 1

Pokémon that are Paralyzed have a 25% chance of not moving that turn. So, we simply do (1/4)^12 (for the number of turns) and we get 1/16777216.

Answer 2

I'm pretty sure it's something like 0.000000000001/1200, either that or 0.000000000001/1200
That's insane.
