WebSolution. P r n: P r n represent the permutation. The permutation is the arrangement of the items into some sequence or order. The number of ways of arranging r items from a set of n items is: P r n = n! n - r! C r n: C r n represent the combination. The combination is the selection of the items where the order of the items does not matter. WebTherefore, the probability of getting exactly 7 heads is 0.193. Example 2: A coin that is fair in nature is tossed n number of times.
