re:
You counted drawers to get your sample size. I counted whole cabinets.
Why am I wrong? (because you get the wrong answer is not acceptable,
although it is pleasantly silly :-) :-) :-) )
---
For the umpteenth time, because each drawer is equally likely to have been
selected, but the cabinets are not equally likely to have been selected.
You can use whole cabinets, provided you count the one with two gold coins
double.  If you still don't understand, don't bore the net with it.
