Then take the pile of 20 coins and flip them over. You will now have the same number of heads in each pile.<br /><br />Explanation: If the pile of 20 coins had x heads in it (before you flip them), then the pile of 80 coins had 20-x heads. The pile of 20 had 20-x tails. <br /><br />Flip the pile of 20 coins over, and you now have 20-x heads, the same as what is in the pile of 80 coins.Anonymoushttps://www.blogger.com/profile/18153935609499338685noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-77124031109377794272010-03-29T13:10:16.101-04:002010-03-29T13:10:16.101-04:00He turned all the coins on to their sides - one co...He turned all the coins on to their sides - one coin every 3 seconds may be a little quick, but if your life depended on it daresay it could be done!!Richnoreply@blogger.com
