You're in a game show where's 3 closed doors. Behind one of them is your dream prize (what ever it is). You pick one door (which ever). After that the game show host opens one of the other doors that you did not pick - showing that your prize was not there. Two doors are left: the one you picked and one you did not pick. Game show host gives you a chance to change your mind - to pick the other door. 

Will you pick the other door or stay with your original choice? Post in comment why.

Lol I've heard this question like 6 times. There's actually a mathematically correct answer.

Most people figure that there's 2 possibilities: either you choose the right door first and switching is bad, or you choose the wrong door first and switching is good. So switching is 50/50 and there's no point doing it.

The simple error everyone makes is forgetting that there's more wrong doors than right ones. The door you choose first is wrong 2/3rds of the time, so switching is right 2/3rds of the time.

Close but you're missing one major part of the riddle. I don't want to spoil the answer :P

Statistics professors really love this question because it's the best example of how unintuitive statistics can get. Almost every class with a lot of stats opens with this.

 
1) Zeno's paradox:

Case: You set up a race between Achilles (very fast runner) and a tortoise (ultra slow crawler). The distance is infinite or until Achilles passes the tortoise. Neither one will get tired during the distance and both will keep moving with the respective speeds as constants.  In addition you will give tortoise a head start of 10 meters. They start at exactly the same time. Who wins the race?

2) If you aim to fail and you fulfill your goal then do you succeed?

How much wood could a woodchuck chuck if a woodchuck was driving 75 mph down the 405?

Lots

10,975,431 cubic meters 

None, because he is focused on the road

Woodchucks can't chuck wood you silly.

I just think it would be interesting to see music polls, since I'm a musician.
