The movie 21 Please explain the math.

[ucodegen]

Interesting experiment to think of:

If we have 3 doors, 2 goats and 1 car.
You don’t make a choice on the first sequence.. the announcer just opens one of the goat doors.

What is the probability of choice between the two remaining doors that either is a goat or a car, and how is this example different than the one given earlier.

The real importance it the independence of trails when doing the choosing. We are asking for the probability of the next decision, not the probability of the pattern of events leading up to the choice.

21 was the lamest movie ever. Get a big name star, throw in some people, make a crappy film and market it like it’s tha shiznit… That should be the description on the cover of this movie. Or “amateurs’ first try to make a movie, somehow get Kevin Spacey to star”.

[quote]I don’t know why some of you people are arguing against the 2/3 answer. It IS the correct answer, whether you understand the logic or not.

People who study probabilities for a living have said this is the answer. All you amateur naysayers should just capitulate and move on…:-)

LOL…I chuckle a bit here, because I had the same feeling.But, thankfully, a lot of you aren’t responsible for engineering things we depend on. Just kidding.

Anyway, don’t mean anything by it. Take a probability class, and then take a stochastic processes class. Much of this is required especially for information theory and communication systems. I guess it’s also applicable to finance, but I don’t know much about that subject.
