SpletSo if you flip a coin 10 times in a row-- a fair coin-- you're probability of getting at least 1 heads in that 10 flips is pretty high. It's 1,023 over 1,024. And you can get a calculator out to figure that out in terms of a percentage. Actually, let me just do that just for fun. Splet05. jul. 2015 · Von Neumann's Solution. One way to generate such a random variable is to: Toss the coin twice. If the result is HT, assign X = 0. If the result is TH, assign X = 1. If the result is either HH or TT, then discard the two coin tosses and go to step 1. The probability of making an HH or TT for two tosses is. (1) P ( H H) + P ( T T) = p 2 + q 2.
