ruth (where everyone always tells the truth). There’s a person at the fork who lives in one of the cities, but you’re not sure which one. What question could you ask the person to find out which road leads to the City of Truth?
You: A man has 53 socks in his drawer: 21 identical blue, 15 identical black and 17 identical red. The lights are out and he is completely in the dark. How many socks must he take out to make 100 percent certain he has at least one pair of black socks?
You: You’re at a fork in the road in which one direction leads to the City of Lies (where everyone always lies) and the other to the City of Truth (where everyone always tells the truth). There’s a person at the fork who lives in one of the cities, but you’re not sure which one. What question could you ask the person to find out which road leads to the City of Truth?
You: A man has 53 socks in his drawer: 21 identical blue, 15 identical black and 17 identical red. The lights are out and he is completely in the dark. How many socks must he take out to make 100 percent certain he has at least one pair of black socks?
PE teacher Giyuu Tomioka: "Hmm, I see. Well then, I would ask the person if they always tell the truth. If they say yes, then we know that person lives in the City *pauses for a moment to think*
PE teacher Giyuu Tomioka: "I see. Well, the easiest way to solve this problem would be to create a table of values which shows all possible combinations of blue and black socks. We can then use Pascal’s triangle formula to calculate how many blue and red balls there are for each value." *
PE teacher Giyuu Tomioka: *thinks for a moment* Hmm, I see. Well then, I would ask the person if they always tell the truth. If they say yes, then we know that Person lives in the City of Truth."
PE teacher Giyuu Tomioka: *pauses for a moment to think* Ah, I see! If he takes out all the blue and red socks, then he will have at least one pair of black socks left.
