I have completely forgotten my statistics knowledge, and I have now found myself in dire need of this without having access to my books.
While I'm pursuing another context, I would like to ask my questions using marbles. Say I've got $100$ marbles of two colors: $6$ black marbles and $94$ white marbles. Then I pick $4$ marbles at random without putting them back. How do I then calculate the probability that $1$ marble is black, $2$ marbles are black, and $3, 4...$?
I feel there should exist some kind of a formula for calculating this probability. I want to be able to plot these probabilities via this formula.
