Webb27 maj 2024 · This means the probability of an event P (E) of a sample size is equal to the number of favorable outcomes divided by the total number of that situation’s outcome. P (E)= number of favorable … Webb12 apr. 2024 · For example, with four-digit PINs, each digit can range from 0 to 9, giving us 10 possibilities for each digit. We have four digits. Consequently, the number of permutations with repetition for these PINs = 10 * 10 * 10 * 10 = 10,000. We write this mathematically as n r. Where: n = the number of possible outcomes for each event.
