You have a large number of friends coming over and they all get thirsty. Your first friend asks for 1/2 a cup of water. Your second friend asks for 1/4 a cup of water. Your third friend asks for 1/8 a cup of water, etc.
How many cups of water do you need to serve your friends?

Makes me wonder if they are really that thirsty!
Infinitely less than 1 cup total
Just one, for there would never be asked something that would make the total amount be over or even equal to 1
One cup. This is Zeno’s paradox. Starting with 1/2, the limit approached when adding an infinite number of successively halved fractions is 1.
Howard, you are today’s winner!
Just one. If your friends kept asking for water like this forever one cup would be enough.
However many cups there are friends. Who wants to drink from the same cup as somebody else? (although you really only need one)
