1. The problem statement, all variables and given/known data If a coin is tossed 200 times, what is the probability of getting 5 heads in a row? 2. Relevant equations 3. The attempt at a solution I know that the probability of getting 5 heads in a row for the first 4 flips is 0. I don't know what to do with that information. 1 - [(0.5)^5 * (0.5)^195] ? I used this streak simulator: http://www.pulcinientertainment.com/info/Streak-Calculator-enter.html#ev-runs And the probability is 0.965903381259682.
