“How is it possible that I got all of the ansrong? Youthat in order to win the bet! There’s no other reason for that!” Yang Wei glared at Zu An angrily He was confident that he should have gotten at least ten questions correct He could never accept that he had actually gotten everything wrong
“Indeed! How could Teacher Yang possibly get everything wrong? He’s our acade too far, lying just to win the bet It only sho despicable he is as a person!”
Zu An didn’t lose his temper despite all of the criticis Wei had just cohten you on your ht answer is 2 and 2, and yet you wrote 10 and 15 Youthat you’d so Wei’s face heated up in euessed two randootten ht about the probleoing to adical Given these conditions, how can anyone possibly deduce the answer?”
“Oh, is that so?” Zu An shook his head disdainfully
“Since you don’t understand it, allow hten you Person A knows the sum of the numbers, but he doesn’t knohat the two numbers are If the sum of the numbers is either 2 or 3, he would immediately know that the two numbers are (1, 1) and (1, 2) respectively Similarly, if the sum of the number is either 40 or 39, he would know that the numbers are (20, 20) and (20, 19) respectively Therefore, the possibilities for the sum of both numbers is narrowed down to be between 4 and 38
“Let’s take 4 as an example If 4 is the addition of both numbers, the two numbers could possibly be (1, 3) or (2, 2), so A is unable to determine which is correct
“Now, let’s look froot was a prime number, namely 2, 3, 5, 7, 11, 13, 17, 19, so on and so forth, he would be able to deduce right away that the numbers are 1 and the number itself Those are the only two factors after all Since he was unable to deduce what the nuht ae can eliminate all pri that the sum of the numbers is 4, and the product of the numbers isn’t 3—which is likely, since B would immediately know the answer if it were—it only leaves the combination of (2, 2) that fulfills the criteria
“There are other combinations of two numbers that sum up to more than 4, such that A is unable to deduce what the two nu deduction too”
After his lengthy explanation, Zu An shook his head and sighed deeply “See, as long as you had the right direction in otten the answer on your first try Isn’t it simple? That’s why I chose to put this question first Who knew you couldn’t even solve such a sian gossiping aic is pretty simple now that he has explained it”
“Tsk, eren’t you able to solve it then?”
“I just wasn’t able to think of it on the spot! I ht either!”
Yang Wei’s face reddened at the da students “Fine, let’s take it that I answered this question wrongly out of carelessness What about the next question, then? Isn’t the probability the same noabout that!”
That was the question that he was the reement “Indeed, the probability should be the same no matter which door is chosen Whether he chooses to switch to another door or not shouldn’tWei’s words were in line with cohed deeply and reet this question wrong, but how could an arithmetic teacher like you make the same mistake too? This sure is Hai”
His condescending attitude so angered Yang Wei that he was on the verge of exploding “Why don’t you put away that ic?”

Zu An finally got around to his explanation “Nothe treasure is one-third In other words, the total probability of the treasure being in the two re doors is two-thirds If I open one of the two doors to show an e behind the only re unchosen door be two-thirds? Given that, you should definitely change your choice of door since the chances of getting the treasure are higher!”
“Rubbish!+” said Yang Wei “The probability of each door having the treasure behind it is independent It should all be one-third How could one of them suddenly become two-thirds?”
Zu An shook his head in response “I fully expected that someone of your IQ wouldn’t be able to understand such coic Well, letthat there are 10,000 doors before you, and only one of them has a treasure behind it If you choose any of the 10,000 doors, your chances of getting the treasure is only 1-in-10,000, right? With such probability, it’s alht It’s al 9,999 doors
“So, if I open 9,998 of the re 9,999 doors and show that they are all e to switch to the other re door?”
“Of course I would switch!” replied Yang Wei without ht after he responded, hisabout that?
Zu An nodded in satisfaction “As expected of an arithh It looks like you aren’t beyond salvaging yet”
Stea Wei’s head It sounds like this fellow’s praising ?
