Crazy weather channel math.
Notice anything odd about The Weather Channel's forecast for tomorrow? "A stray shower or thunderstorm is possible... chance of precipitation... 0% ! WTF weather channel? Talk about covering your ass! I wonder if any of the forecasters at The Weather Channel have taken a class in statistics. As I learned it, a 0% chance means that that something is not possible!

hate to tell you but things with probability zero do happen!!!!!
Take a number uniformly distributed between 1 and 2. [real number].
What is the probability of picking exactly 1.5? Well it's ZERO!
There is a non-zero probability of picking a small range from [1.5-eps, 1.5+eps]. As eps->0, so does the probability!
Same argument applies for ANY integer between -infinity,+infinity]. (Infinitely more reals than ints).
