a difficult problem for you to ponder

http://en.wikipedia.org/wiki/Monty_Hall_problem

"Mantos", a boy from my class two years ago suggested you guys have a go at this tricky problem.. the attached wikipedia link has the solution included.


and remind me to teach you about "petals around the rose" - another fascinating problem...

that is really confusing!!!
i think that there is an equal possiblity of getting the car because you do not know which door the cra is behind. therefore the answer depends on luck and probability.

no i dont think so... coz if you choose door 1 or 2 the host will still show you door 3 so basically youre just guessing the answer between 1 & 2

primprim said...

i don't understand

Mr Woody said...

i'm very impressed that you two have had a go at solving it and are discussing the mathematical probabilities, etc. well done!

i think you've got a slightly better chance to switch to door two

Anthony said...

MUHAHAHAHAHAHAHAHAHA!

Kitty Kat said...

no its 50 50 I'm sure 50% I'm 99% sure think of it like this three doors 2 goats and 1 car you know 3 is a goat so now there is 1 goat and 1 car your just as likely to get a car as you are a goat so whats the point in changing?

Anthony said...

Try thinking about it with more then three doors like 20 doors. Theres only a car behind one. You pick on and they guy opens 18 doors and leaves one. Do you still think its 50/50 then?

Kitty Kat said...

no because there is then 1 car and 17 goats. see. its only 50 50 because you only have 2 choices.

Anthony said...

Yes but in the first place you have a 19 out of 20 chance to pick a goat and a one out of 20 chance to get a car. So if you are more likely to get a goat and then the guy opens all the other ones with goats behind except for one door it is much more likely that it will be the car because you only have a 1 out of 20 chance to pick the car door, so you should change. It's the same situation with 3 doors except you don't get that much of a bigger chance by changing but you still have a better chance.

Kitty Kat said...

I still dissagree.

Camman said...

lol no one trusts anthony

primprim said...

does the game "petals around the rose" depend on the spelling of the game?
