door #'s: 1 2 3

doors: O O O

okay each door has a 1/3 chance; but the two on the left have 66% chance.

So now say we pick one for example, door 3 okay so we say that it has a 33% chance.

and i was looking at using this with big numbers like 10 doors so: we have ten doors

1 2 3 4 5 6 7 8 9 10

each one has a 10% chance

now say we open door 9, at this point, you only have a 1 in 10 chance of getting it right. now next step:

lets say we open all the doors except for door 7 and door 9 so looking at this problem with all the doors you would think it's in door 7, BUT thats not true now we just have two doors:

7 9

O O

okay and now they both have a 50/50 chance.
