Permutation
nPr = , where r is the size of the subgroup taken from a set with n elements.
Combination
= , or nPr /r!, where r is the size of the subgroup taken from a set with n elements.
Probability
Total Elements of Overlapping Sets
If two subsets of a set share elements, the equation that governs the total number of elements in the set is:
Total Elements = Group A Elements + Group B Elements + Neither Group A nor Group B Elements – Group A and Group B Elements
