Why is there a probability of 2/3 instead of 50% in the puzzle with fair coin and two-headed coin?
I see. But shouldn't the probability of getting a head or tail be 50% on each flip regardless of how many times the coin is flipped?
Yes, that is correct. The probability of getting a head or tail on each flip of a fair coin is indeed 50%. However, in the puzzle, there are actually two different types of coins being used - a fair coin and a two-headed coin.
