WebOct 23, 2024 · Finding probability using the z-distribution. Each z-score is associated with a probability, or p-value, that tells you the likelihood of values below that z-score occurring. If you convert an individual value into a z-score, you can then find the probability of all values up to that value occurring in a normal distribution. WebDec 28, 2024 · In statistics, you can easily find probabilities for a sample mean if it has a normal distribution. Even if it doesn’t have a normal distribution, or the distribution is not known, you can find probabilities if the sample size, n, is large enough.

WebRule 1: The probability of an impossible event is zero; the probability of a certain event is one. Therefore, for any event A, the range of possible probabilities is: 0 ≤ P (A) ≤ 1. Rule 2: For S the sample space of all possibilities, P (S) = 1. That is the sum of all the probabilities for all possible events is equal to one.
