Which means they simplify the problem as follows: 6÷2(1 2) = 6÷ 2(3) = 6÷6 = 1.You pick door #1, and the host, who knows what's behind the doors, opens another door, say #3, and it has nothing behind it.He then says to you, "Do you want to stick with your choice or switch?What people get wrong here is thinking that because there are only two doors left in play, you have a 50% chance your first choice was correct. There's still a 1 in 3 chance you picked the right door and a 2 in 3 chance you picked an empty door, which means that when the host opened one of the empty doors, he eliminated one of the WRONG choices and the chances that the prize is behind the last closed door is still 2 in 3 — double what the chances you picked the right door at first are.So, basically, by switching your door choice, you're betting on the 2 in 3 chance you picked the wrong door at first.Some people are POSITIVE the answer is 1 and some people are absolutely sure the answer is 9.

If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake? before you sit down to actually do it and find you have no clue how to solve it.Then there are the problems that make you feel like a math whiz when you solve it in 2 seconds flat — only to find your answer is WAAAAY off.
