Webb17 aug. 2024 · The probability of r successes in n trials is n C r (p) r (q) n-r, where p is the probability of success on a given trial and q = 1-p. In this problem, n = 6, r = 3, p = q = 0.5. … WebbWe should use the “binomial distribution” because the “probability” of obtaining “successes” in each trial is 0.30. All the “trials” are “independent” of each other. Only “two outcomes” are possible i.e. “success” or “failure”. Let “X” be the “number of successes” in “n” “number of trials” with ...
