Too simple Jacob, the brollys may LOOK the same, but each person wants their own brolly.

Come on Bride - think about it!

You can have up to three clues - but I'm sure you won't need them!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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 unbrella?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Zero percent.

as you say very simple if 2 people get the right one the other has to be right

The devil is in the detail...

Assuming that each person takes the umbrella away after they have selected it, i get the following:

Four scenarios

Person 1 picks and its wrong
Person 2 picks and its wrong
Person 3 picks and its wrong
0% chance of 2 people getting the right umbrella

Scenario 2

Person 1 picks and its right
Person 2 picks and its wrong
Person 3 picks and its wrong
25% chance of 2 people getting the right umbrella

Scenario 3

Person 1 picks and its wrong
Person 2 picks and its right
Person 3 picks and its right
40% chance of 2 people getting the right umbrella

Scenario 4

Person 1 picks and its right
Person 2 picks and its right
Person 3 picks and its right
100% chance of 2 people getting the right umbrella

So the average of 100%, 40%, 25% and 0% would be 55%

The % chance that 2 people will walk of with their own umbrellas would be 55%....

Or do i need a clue, it is Sat morning after all?!!?!

poss tooo analytical from the FI

I am going to make coffee thats nice and easy!

**zazen999** · 20-12-2008, 02:42 PM

the clue is the word ONLY...

**lottie dolly** · 20-12-2008, 02:43 PM

two percent

**Nicos** · 20-12-2008, 02:46 PM

I'm with Andrea with that...if 2 peeps have their own - then so does the third- so you can't have ONLY 2 peeps- has to be either one, or all three

so 0% is my answer

**where2start** · 20-12-2008, 02:50 PM

So i didn't make coffee, still thinking about it!

As there are four possible scenarios and two of them would result in 2 people getting the right umbrella would it be 50%
