Is there an efficient way to identify which distribution a probability is in? I been doing the chapter exercises to no avail... I keep mixing out geometric and negative binomial... & sometimes we get a None of the above answer !!!

Can someone brief me regarding the important criterias for each distribution? I already know how to use the formulas and stuff, but I don't know how to get from not knowing which distribution apply to which does (so I can use the appropriate formula).

Thanks!
