Difference between binomial distribution and geometric, hypergeometric etc
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?
