No two snowflakes are identical... tautologically false. Statiscally probable.

Depends on the sample size and the margin of error and how you define the parameters of the study and resultant probability.

Or, one could say, who gives a shit?

Fact is, I'll bet there were a million of the little bastards in my driveways this past winter that were IfuckingDENTICAL on accounta there were billions and billions of them. But, I will never know because they were chewed up and spat out by the snowblower before I could inspect them all... and I hope each and every one of the little fuckers died a severely painful demise.

NOW, I gotta mow the millions of blades of grass in the lawns and I really don't car if they even look the same shade of green. That's if the trillions of drops of rain being blown sideways by high winds will ever stop.

Here's a statistic for you, sample size of one, no standard deviation... Mother Nature is a bitch.
