This is not a question its just about something I read recently regarding repeated prime factors. The probability of a non-prime number having repeated prime factors is said to be 6 / pi^2.

Isn't it amazing that the circumference of a circle is involved in a probability formula? I expect there are more of these - pi is also a part of the Normal Distribution function.
