How to easily identify different probability distributions? I am studying currently further option mathematics but i cant identify which distribution to utilize in which question? (these are genearlly word questions?)
We are currently studying geometric,poisson, binomial, negative binomial. I was wondering if someone can explain how to identify which problem uses which distribution?

Binomial distributions are used for boolean variables, i.e. variables where they can either be true/false, negative binomial is used to model the number of successes(true) before a specified number of failures. Geometric distribution has two different types (https://en.wikipedia.org/wiki/Geometric_distribution). Taking the first definition, its used to describe how many trials you would expect to do before you had your first success. The Poisson distribution is used to describe the number of 'events' you would observe in a given time.
