I have a die with 121 sides
I roll it 36 times
What is the probability of hitting the numbers between 1 and 12 including 1 and 12 in at least 12 of the 36 rolls?

An explaination of the calculation would be appreciated

Thank you

Edit:at least

google binomial probability. pretty straight forward. essentially you look at the probability of rolling 1-12, then you look at the number of possible outcomes (eg: success first 12 rolls, failure the rest, success first 13 rolls, failure the rest, etc).

no idea why you posted in programmer's haven.
