The total of withdrawals in the left-hand column must always equal $100, but is purely coincidence that the total of the right-hand column is close to $100.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-15628310.post-72673151734966899142007-12-11T22:24:00.000-05:002007-12-11T22:24:00.000-05:00You all saw right through it.You all saw right through it.Mikehttps://www.blogger.com/profile/18153935609499338685noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-73209760299456861712007-11-28T19:02:00.000-05:002007-11-28T19:02:00.000-05:00However, if he always took out half of the money t...However, if he always took out half of the money that he had remaining in his account, the two columns should add up to the same number.

This just is just coincidental that it is so close to the actual value (mostly because you did a pseudo-binary series type pattern -- like how 1+2+4+...+2^n=2^(n+1)-1).<BR/><BR/>A good counterexample would be to think about if this bank customer withdrew $1 at a time, 100 times. Then, his "balance remaining" column would look like "$99, $98, $97,...", which, if totaled, is way bigger than $100.Abehttps://www.blogger.com/profile/04424868492071587450noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-1572213566919861272007-11-28T10:13:00.000-05:002007-11-28T10:13:00.000-05:00deposits and withdrawals typically don't post unti...deposits and withdrawals typically don't post until 18:00.Deekinhttps://www.blogger.com/profile/04421086747469575534noreply@blogger.com
