''In general we know;
So the odds there are 4 aces in deck Y are;
''
I have been given this maths on another forum, I do not know if this is correct. Is this correct please?

These equations look good to me. I don't like the phrase "...so the odds there are 4 aces in deck Y are..." but I might be missing the context, or they might have said something they did not mean (typically the probability that a deck of cards contains 4 aces is around 100%). At just a glance, it looks like the second equation is for calculating the probability that there are 4 aces in a deck of 52 cards that was constructed by picking 52 cards from an infinite number of decks...

The first equation represents 4 aces in a standard deck of 52 cards an x-axis
the second equation represents 52 random top cards (Y) from 52 decks , showing that y only has a 20.3% chance of containing 4 aces and being even to X.
Some people have understand my poker theory and it looks like I might be correct after all.
Thank you for confirming the maths. Alan's link lead me to the maths I needed, an auto correlation link that lead me to cross correlation and Time series analysis.

I think they used this but for 52 rather than 100 -
