Each token has exactly one face called "h". When flipped, tokens 1,2,3... to 14 land with...(contd.) probabilities h(1),h(2),h(3)...to h(14), respectively. When the person flips each of the 14 tokens exactly once, the probability that an even number of tokens land heads is exactly 1/2. Must there be a k between 1 & 14 (inclusive), for which h(k)= 1/2 ? Kindly prove it.
