<p>This was done in an old forum and it was pretty fun, so I though I'd give it a shot here. Basically, I'll post a riddle/problem or something and you guys can try to solve it. First person to get it right (with good reasoning) will supply the next problem/riddle. Also, no cheating! I'm sure lots of these answers can easily be found on the internet, but let's stay legit.</p>
<p>I'll start:</p>
<p>"Suppose you're on a game show and you're given the choice of three doors. Behind one door is a car; behind the others, goats. The car and the goats were placed randomly behind the doors before the show. The rules of the game show are as follows: After you have chosen a door, the door remains closed for the time being. The game show host, who knows what is behind the doors, now has to open one of the two remaining doors, and the door he opens must have a goat behind it. If both remaining doors have goats behind them, he chooses one randomly. After the game show host opens a door with a goat, he will ask you to decide whether you want to stay with your first choice or to switch to the last remaining door. Imagine that you chose Door 1 and the host opens Door 3, which has a goat. He then asks you "Do you want to switch to Door Number 2?" Is it to your advantage to change your choice?</p>
<p>Yes it's to your advantage. There is a one in three chance if you stick with your original choice, a 1 in 2 if you switch. Am I correct? :P</p>
<p>"Yes it's to your advantage. There is a one in three chance if you stick with your original choice, a 1 in 2 if you switch. Am I correct? :P"
Nearly, though your fraction doesn't make sense lol. Explain your answer though! :) And once you do, post a new problem. Thanks.</p>
<p>hahhaha i loved 21</p>
<p>It's simple probability.
2 doors have goats, 1 has a car.
When you make a choice, the prob. that u chose the car = 1/3 = 33%
and prob. that u chose a goat = 2/3 = 66%
After the host opens another door and shows u the goat behind it, if you stick with your original choice, the probabilities won't have had any effect on them. But if you switched doors now, you'd have a 50% of getting the car (theoretically), because only 2 doors are left now.</p>
<p>This is why it's theoretical and may not actually happen all the time, which is why you gotta control your emotions and not let them get in the way. something that they kept repeating in 21 too. lol</p>
<p>This is known as the the monty-hall problem btw</p>
<p>Yeah, you guys have got it. Simply put, if you stay with the same door, you've got a 1/3 chance of getting the car. If you switch to the remaining door, you've got a 2/3 chance for the car.</p>
<p>I didn't get this from 21 by the way. It was on Savant
s site.</p>
<p>This next one is pretty easy. Remember, no Google!</p>
<p>"Consider a situation in which a father and son are driving down the road. The car collides with a tree and the father is killed. The boy is rushed to the nearest hospital where he is prepared for emergency surgery. On entering the surgery suite, the surgeon says, "I can't operate on this boy. He's my son."</p>
<p>How is this scenario possible? This one isn't too difficult and rather well known I believe.</p>
<p>The surgeon is the boy's mother.</p>
<p>Yep. You got any puzzles spidey?</p>
<p>I have another one. A man is born on 02/29/68. What year will his fortieth birthday occur?</p>
<p>count leap years... gaps of 4.. im too tired to do it right now lol. It's late night cya!</p>
<p>Btw, for leap years u also have to check divisibility by 400! Could make this longer lol</p>
<p>^Well technically, since the 29th only happens once every four years, his fortieth birthday would occur in 2128... however, since i don't know of anyone who has managed to live 160 years, I don't think that this man will ever live to see his 40th birthday.</p>
<p>Riddle:</p>
<p>"I turn polar bears white </p>
<p>and I will make you cry. </p>
<p>I make guys have to pee </p>
<p>and girls comb their hair. </p>
<p>I make celebrities look stupid </p>
<p>and normal people look like celebrities. </p>
<p>I turn pancakes brown </p>
<p>and make your champagne bubble. </p>
<p>If you squeeze me, I'll pop. </p>
<p>If you look at me, you'll pop.</p>
<p>What am I?"</p>
<p>If anyone gets this right away, they are Googling! :)
This is a very hard rhythm without taking it a step at a time.
Whoever answers correctly, please post something of your own! Thanks.</p>
<p>Lol, never mind I just realized I typed it out wrong. Spidey, post a new one.</p>
<p>iv read this one some were else. You forgot the part about the harverd school, and the little kids, you need that to figure out the answer is “no”</p>
