Need to understand various probability subjects. Been procrastinating during semester. Need help with understanding probability distributions (joint, conditional, marginal,hypergeometric, binomial, covariance Concepts: all probabilities distributions from discrete variables.How the are LINKED. By making analogies or links I understand better. Like why the expected value is named this way and how it replaces the mean. Even basic concepts like random variables (because in math and stats, if you miss one thing, then the further you go you will not understand.

Need quick formulaproofs (my way to understand better). Need to understand the why, (the concept), the logic behind it. Would like short examples to illustrate formulas.

It's a little bit disorganized.

Thanks.
