The possible outcome of flipping the coin to get 5 heads consecutively 5 times and a tail in the sixth outcome would be
[tex]\frac{number\text{ of possible outcome in the sixth flip}}{\text{total expected outcome in the sixth flip}}[/tex]The number of getting a tail the sixth time from either getting head or a tail is one out of two
[tex]\frac{1}{2}[/tex]
Hence, the theoretical probability that it will come up tail is 1/2, option B
