Suppose I have the following sequence in an event: BABCCABAA There are 9 elements in the sequence and I want to find the number of arrangements I get can out of this 9 elements. The order does matter but because there are repeated elements such as 4A's, 3B's, etc, it becomes not as easy as just 9 factorial. For example, the following 2 are the considered only one arrangement: $BA_3BCCA_4BA_1A_2$ and $BA_1BCCA_4BA_2A_3$ So how can I find the number of arrangements when there are such repeated elements in it?
