How do i figure out probability

WebFeb 13, 2024 · The binomial probability formula is: P (X=r) = nCr · pʳ · (1-p)ⁿ⁻ʳ, where r is the number of successes, and nCr is the number of combinations (also known as " n choose r "). In our example we have n = 7, p = 1/12, r = 2, nCr = 21, so the final result is: P (X=2) = 21 · (1/12)² · (11/12)⁵ = 0.09439, or P (X=2) = 9.439% as a percentage. WebThe experimental probability of an event is an estimate of the theoretical (or true) probability, based on performing a number of repeated independent trials of an experiment, counting the number of times the desired event occurs, and finally dividing the number of times the event occurs by the number of trials of the experiment.
