Thanks for the answer and explanation, makes sense to me.

 comment Probability of card decks being in the same order for N shufflers over X amount of time?
What is the equation you are using to calculate it called? And which product sign are you referring to? m(m-1)/2 is the total # of pairs, but I don't see the dependent events factor of (correct me if its wrong) (52!)!/(52!-m)!

Actually, wouldn't it be (52!)!/(52!-N)!

I figured that assumption was wrong somewhere and had forgotten about the birthday paradox. So I just need to multiply p2 by 52!/(52!-Np)?

 comment For all w, CDF of y at w is greater than the CDF of x at w. Prove that the probability ( y < x ) >= 0.5
It's for all w and yes we wanted P(y<x) > 0.5 but Fy(w) > Fx(w), so it should logically work itself out. Why is P(y < x) equal to the line under Fy(Fx) ? Why not Fy(fx)? And what do the functions mean without something feeding in like (w)?

Any distribution, and I believe they were independent if it matters.
