This is a slight variant on a normal probability of getting k successes in n draws type question that I can't seem to find guidance for.
Suppose we have a standard 52-card deck and we want to calculate the probability of drawing k number of Hearts in x amount of rounds. Each round, we draw 5 cards at a time, and keep the successes (in this case any Heart), putting the non-successes back in and shuffling the deck before drawing another 5. How do we calculate say, the probability of drawing 3 Hearts in 5 rounds of this?
I know to use a hypergeometric distribution for thinking about drawing without replacement regardless of success, but I was wondering if there's a distribution (and corresponding pmf for calculating probabilities) for this type of case. I can answer this kind of question fine with simulation, but I'm very curious to know how to approach this mathematically. I can somewhat envision a tree with "compounding" hypergeometric distributions, but I'm having trouble generalizing/formalizing it.
Say we draw $h_1$ hearts the first time, $h_2$ cards the second time, and $h_3$ cards the third time. The probability of this is $$ {{13\choose h_1}{39\choose 5-h_1}\over{52\choose5}} {{13-h_1\choose h_2}{39\choose 5-h_2}\over{52-h_1\choose5}} {{13-h_1-h_2\choose h_3}{39\choose 5-h_3}\over{52-h_1-h_2\choose5}} $$ For a particular number $h$ of hearts, you have to sum the foregoing over all $h_1+h_2+h_3=h.$
It doesn't look like there's much possibility of simplification to me.
EDIT
Computation gives these probabilities:
