Suppose we have a coin that is assumed to be fair. If we flip the coin one time, the probabilitythat it will land on heads is 0.5. Now suppose we flip the coin 100 times and it only lands on heads 17 times. We would say that the likelihoodthat the coin is fair is quite low. If the coin was actually fair, we would expect … Zobacz więcej Suppose we have a spinner split into thirds with three colors on it: red, green, and blue.
