Probability of anything...

Have you ever wondered what's the probability of anything occurring in this world? I'm sure most of you might have dabbled with some probability concepts at some point during your formal learning years. Depending on what kind of a person you are, you might have either been a genius at it and totally relished it; or you might have been like me - you might have been insanely incompetent at it and absolutely loathed it.

It's not that I didn't put in any effort to make some sense out of probability concepts - I rolled a lot of six sided fair (and unfair) dice at least a few thousand times; I tried picking out different cards from a very cheap looking deck of cards; I tried waiting at a bus stop to "sample the space" that the bus arrived in; I even managed to board the same bus to visit a shop on the other end of the city that sold objects of different colours and shapes - I bought these and put them in a big box and tried to pick one out randomly. However, in spite of doing all this, I just couldn't fathom this seemingly ridiculous concept.

And then it happened! I had it nailed to a T. The utter obviousness of this entire affair was just mind blowing. The probability of anything in this world is 1 by 2, or 50%! Just think about it for a moment - the probability that anything will happen is exactly 1/2 - either it will happen or it won't. I can back this claim with more examples as illustrated below -

  1. Hey what's the probability that the card I pick is an ace of spades - 50%, either you will pick it or you won't.
  2. Hey what's the probability that the cafeteria food won't suck today - 50%, either it will suck or it won't.
  3. Hey what's the probability that the hot chick sitting on the 2nd floor in office is from Poland - 50%, either she is from Poland or she isn't.
  4. Hey what's the probability that Neal 'n' Nikki (the film) will get a cult status - I would treat this as an exception to the rule - I think we all know the probability of this one!

I could go on with many more examples here but hopefully you get the point. On realising this obvious truth, I have started to feel a lot more comfortable about throwing in probability concepts in my everyday talk and I strongly encourage you to do the same. I use lines like "Yeah boss, there's a good probability that I'll have that presentation ready by tomorrow EoB" a lot more frequently in my emails. So far, no one's complained.

Now before I sign off, can some one tell me what's the probability that the actual probability theory will be changed to adapt to my concept?
