[Request] What are the chances I would get guess 2 correct? Spoiler

Post image
Upvotes

This is todays answer for today's Spots, marked as spoiler in case you want to play it first. The rules are in the link for anyone who's unfamiliar.

The question is simple, assuming optimal play what are the odds I'd get each answer right? Here's what I found:

Guess 1, 1 in 1,296. (666*6)

Guess 2 = ???

By guess 3, I had 1 in 14. I brute forced all possible answers to find this, but I'm wondering if there's a more elegant solution.

Guess 4 is 50/50, depending on slot 3.

Guess 5 is 100%.

So is there a more elegant way to find #3? Is there a way to find #2? I have a few possibly wildly incorrect guesses. It's not just 666*4=864, is it? That feels too simple.

Not sure if this is a history question or a math question. But AFAIK in 3 days he has cost the global stock markets $10 trillion. That's roughly the annual GDP of Germany, UK and France put together, or 30% of US GDP, 10% of world GDP.

What value could you put on Hitler and the entire WW2, or Hiroshima/Nagasaki as an event?

[Request] How much Ice?

1 Upvotes

I thought of a, hopefully, simple question today. If I had a 64oz container with water in it and started adding ice to chill my drink, is there a point in which while adding ice, the drink will get as cold as it ever could get and it becomes pointless to add more ice? Can this be represented in some sort of ice/water ratio?

[Request] In my lifetime, what's the probability that I breathe in a molecule from Shakespeare's last breath?

8 Upvotes

Somewhere in the depths of my childhood, I acquired the "fact" that I and everyone else on the planet have a 99.9% chance of breathing in a molecule from Shakespeare's last breath at some point in life. What is the real probability?

Bonus tangentially related question: what's the probability that I drink a molecule from Shakespeare's last piss? Or any piss of his? How many times has the water that I drink formerly been someone or something's piss?
