Q’s Question

The times they are a-changin’.

This post seems to be older than 19 years—a long time on the internet. It might be outdated.

Quinn McGinnis sent out this email the other day. I love riddles, especially ones that can be deduced logically. I know the answer, can you figure it out?

Hey, I’m doing a bit of a study here..feel free to help me out.

Please try to figure out the answer to this question. If you think you’ve got it, send your answer directly to me. (Do NOT send it to dualbs, send it to quinn@——–.com).

You’re on a game show. The host has put three doors in front of you. Behind one of the doors is $1,000,000. Behind the other two doors is nothing. You pick door number 1. Then, the host walks over and opens door number 2, showing you that nothing is behind it.
Then, he says, "Are you sure you want to choose door number 1?"

You have two options:

  1. Stick with door number 1
  2. 2. Change to door number 3

Which one do you choose? Does it matter? Please explain why.

Quinn also chatted with me on Messenger yesterday and posed this problem, which I almost got:

So you have two dice. And you roll both of them. Your friend looks at them and tells you information about only one die, it landed on "1". What are the chances that both dice landed "1", assuming that your friend told the truth?

I’ll post the answers tomorrow, if I remember.
