Three identical-looking umbrellas are sitting upright in a stand. Assuming the owners don't check their umbrellas' labels, what percentage chance is there that only two people will walk off with their own umbrella?

im a bit late today, aren't I?

Who cares as long as their let me stand under their umbrella when it's raining and aren't greedy fucks that want their dryness for themselves
>>
I bet the answer is some bullshit, like "100% because all three are identical"

Hi wait the answer is 0% because that situation could never occur. If two got the right one, the third one has the right one too

That's right!

If two people manage to grab their own umbrellas, the third person is left with only one umbrella to take: her own!

It's impossible for only two of the three to pick up their own umbrellas.

I'd say 11.11% because each person has a 33.33% chance of selecting their own umbrella. Though the answer to the riddle is probably 16.67% as the first person to grab their umbrella has a 33.33% chance of selecting the umbrella and the second person has a 50% chance of selecting the correct one from the two leftover options. That doesn't take into account that the first person could have selected the second person's umbrella and the second person has a 0% chance of getting it right. Therefore all three umbrellas are a factor for everyone.

What if one person wasn't the owner of any umbrellas and was using a stolen one?
>>
>>37540220
0%
If one person has mistaken their umbrella then so did one another. So it's either everyone grabs their stuff or two pick the wrong ones.

Do I win something for this?
Eternal happiness and fulfillment?
Perhaps a significant other of own? that'd make both mentioned aspects and more.

Currently? No. Maybe one day I could give away a steam game or something for a random correct answer.
