Hello,

I'm confused about the difference between binomial, geometric, hypergeometric, negative binomial, and discrete distribution. When I get a word problem, I always use the incorrect one.

For binomial: it's just the x successes in n trails where the probability of success in each trail is the same right?

but isn't this the same as geometric?

i know that hypergeometic is basically like the binomial except it's without replacement (the prob changes within each trail)

and that the negative deals with drawing the nth time right?

Thank you!
