Webb12 juli 2016 · Explanation: The formal definition of n! (n factorial) is the product of all the natural numbers less than or equal to n. In math symbols: n! = n ⋅ (n −1) ⋅ (n −2)... Trust me, it's less confusing than it sounds. Say you wanted to find 5!. You just multiply all the numbers less than or equal to 5 until you get to 1: 5! = 5 ⋅ 4 ⋅ 3 ⋅ 2 ⋅ 1 = 120 WebbStep 2 To complete the calculation and determine the probability of exactly 2 successes in 4 trials, you would multiply the combinations, 6, by the product of the probability of a success on a given trial, p, taken to the x power, by the probability of a failure, q, taken to the n-x power. The formula, as you’ve seen above, is given as: P(x) = nCx (p)x (q)n-x
