A fair coin lands heads four times. Is tails now due?
H H H H
For independent tosses of a fair coin, the next toss still has two equally likely outcomes.
P(tails) = 1/2
Five specified heads in a row has probability one half multiplied five times: one in 32.
(1/2)⁵ = 1/32
The probability of the next outcome differs from the probability of an entire sequence chosen in advance.
Next toss ≠ whole streak
