Nuclear decay of small amount and by different processes

[ORF]

Hello

I was reading this post,

https://www.physicsforums.com/threads/nuclear-decay-of-a-small-number-of-atoms-calculation.853664/

and I wander if the binomial distribution is still a good model if you have a small amount of nuclei, and in addition they can decay by different processes (each process has its probability, different from the rest).

Thank you in advance :)

Yes, every nucleus will still have an exponential decay. If you want to describe the possible outcomes as well as the probability of decay, you will need the multinomial distribution instead.
