What would be the probability of dealing a deck of 72 cards out in the exact orderly sequence that they were in when they were packaged after they have been throughly shuffled?


Denote 72!=72*71*70*69*...*3*2*1. This is very big number and it represents the number of ways to deal a 72 cards deck. Then the probability we are intersted in is : 1/(72!).
