You are blindfolded before a table. On the table are a very large number of pennies. You are told 128 of the pennies are heads up and the rest are tails up. How can you create two subgroups of pennies, each with the same number of heads facing up, while remaining blindfolded?

take the 128 pennies, flip them over to tails up, divide the pennies in half, then flip the one half over to heads up
On the right track, but not quite. Remember, you’re blindfolded.
I’m not sure, but I’m pretty sure the first thing I would do is count all the pennies to see how many are tail up. Is that part of it?
Simple. Take off your gloves and blindfold
No, and there are no gloves.
Boesner you were very close, perhaps you should revisit.
I don’t know. What is the answer?
First,randomly separate 128 pennies from the rest and flip those 128 pennies. You will get the same number of pennies with heads face up.
