Nov 26, 2011 at 7:41	comment	added	Xi'an		@varty: This is the alternative notation to ${2k \choose k}$, used for instance in French textbooks.
Nov 26, 2011 at 5:53	comment	added	varty		Are you using $C_{2k}^k$ to mean the number of ways we select $k$ items from $2k$ items?
Nov 26, 2011 at 5:49	comment	added	Eric		@varty:$C_{2k}^k$ is the situation when there're equal numbers of flashes of red and blue (where each color has k flashes). Left hand side is the probability you guess correctly under best strategy when you decide to observe $2k-1$ times; RHS is the probability you when you decide to observe $2k$ times.
Nov 26, 2011 at 5:06	comment	added	varty		How would you interpret $C_{2k}^k$? What would selecting $2k$ items from $k$ items mean? Should this term not be $0$?
