A Difficult Riddle

Eminem · 08-21-2004, 07:46 PM

I just solved this problem, which took me about an hour to figure out. It's not really a riddle but since there's no better way to explain it, it will be called a riddle. Anyone who can solve it will get a lot of rep points.

There are 13 pennies on the desk. They are all in one group, 5 of them being heads and 8 being tales. You have to split them into 2 groups with the same amount of heads in both groups (you can flip the coins). The trick is, you have to do it in the dark, not knowing which coins are which.

what do you mean by, "you can flip the coins"

MGselwonK · 08-21-2004, 08:12 PM

i would be surprised and delighted if there was a logical answer to this

my answer is going to be "flashlight" or "pick which ones are head by feeling them"

i mean... that IF you could see them, there would be 5 heads and 8 tails. so by flipping a tail over, you will get 6 heads, then just put 3 heads in one group and 3 in the other.but you cant see them, you cant feel them, because they all feel the same. there is a perfectly logical answer to this, and trust me its hard to figure out

wouldn't you jsut split the coins into two groups, thne fLip one coin. it doesn't matter wihce because if you:

A) flip a heads it will be tails, then there will be 2heads in each group
b) if you flip a tail it will be head, thus being 3 heads in each group

just a quick guess...i will try to actually solve it later...hehe

I was thinking the same thing but realized the problem. Unless you're allowed to see the coins before splitting them into groups, there's no guarantee you'll get 3 heads in one group and two heads in the other group. You could get all five heads in one of the groups.

just feel the ones that your not sure what they are

thats correct, there in lies the problem. and you're not allowed to "feel" them mainer, ive already said that

btw, if you think you've got it, PM me first. i dont want to give it away that fast. i will give the answer if its not solved in a few pages of posts.

Somehow, I think that every penny should be flipped...leaving 8 heads and 5 tails...but that still doesn't solve how to then get the pennies into groups with 4 heads each...

Edit: When you say two groups, does that mean a group of 6 and a group of 7? Do all the pennies have to be in the 2 groups...or could I have two groups of 4 with extras on the side?

all the pennies have to be in 2 groups... but the groups could be 1 and 12, providing that you can prove that there are the same amount of heads.

looks like we got time to waste
maybe putting one on its side will help so there are 12 pennies posible
