WebIn a biased coin, the probability of getting head or tail is unequal. As a result, the probability of occurrence can be anything other than 0.5. For example, if the coin produces more heads than tails, it’s probability will be more than 0.5 else it will be less than 0.5. Flipping a Biased Coin. Look at our Python code below: WebJun 1, 2024 · If the coin is fair it should be quite likely to get 560 heads out of 1000. So we calculate that probability as: Pr ( X = 560) = ( 1000 560) 0.5 560 ( 1 − 0.5) 1000 − 560 ≈ 0.00002. Since the probability of getting 560 heads out 1000 flips if the coin is fair is so very small, I find it very likely to be biased. Share. programs committee agenda
