To see why this is the case, suppose that in your first six draws, you draw all five nickels, and then a quarter. So http://upload.wikimedia.org/math/4/a...0e5193b2b5.png. If we know not just http://upload.wikimedia.org/math/9/8...dc7c4c603f.png, but the earlier values as well, then we can determine which coins have been drawn, and we know that the next coin will not be a nickel, so we can determine that http://upload.wikimedia.org/math/7/0...d51e83a33b.png with probability 1. But if we do not know the earlier values, then based only on the value http://upload.wikimedia.org/math/9/8...dc7c4c603f.png we might guess that we had drawn four dimes and two nickels, in which case it would certainly be possible to draw another nickel next. Thus, our guesses about http://upload.wikimedia.org/math/f/d...18c36fa3ca.png are impacted by our knowledge of values prior to http://upload.wikimedia.org/math/9/8...dc7c4c603f.png.
So do you REALLY want to consider all that in your trading ??
I don't.
silly me
