Hello, i dont know statistics but i watched a video on geometric distribution to learn what happens if a 10% chance occurs multiple times and what the percentage is for something to succeed on any given trial. Luckily, this concept is pretty straightforward using no abstract logic and I believe i was able to calculate if something has a 10% chance of happening, then the chance of that thing to happen on any given trial would be 8.1%. Just need it proofed, thank you.

Do you mean the chance that the thing happens for the first time on the third trial?

#

If so, that's right

#

Yes

#

How would i calculate for any

#

Given trial then

#

Or

You wrote it out

I did?

Sorry i take statistics in college

x is the number of trials, and the probability of that is q^(x-1)*p.

#

So chance of it failing to the power of number of trials - 1) times the probability
