Hi all, just a quick probability question that I'm not sure about. What are the odds of flipping a fair coin and having it come up heads every time 21 times in a row?

Wow what a wonderful contribution.

The probability of any fixed particular sequence of length 21 of heads and tails is (1/2)^21 = 4.76837158 × 10-7.
