Incorrectly.
Here's a simple thought experiemnt, one I've used before. Take a standard deck of 52 cards. Shuffle, and lay them out randomly. The likelihood of any particular hand of 52 is 8.06581752 × 10^67. This is a number far beyond human comprehension...for all intents and purposes, it is impossible. And yet... nothing stops you from laying out those random cards. You could do this impossible thing twenty times an hour, every day of the week. Even though the chances of *that* hand are nil, the chances of *some* hand are effectively unity.
So the next time someone tells you that it's statistically impossible for some biological structure to evolve... keep in mind that it's also virtually impossible to get a particular order of cards. But *something* is clearly virtually inevitable.
But that 'something' CANNOT make the NEXT hand dealt be like itself!
