Lecture 8 MATH1904 Multinomial Coefficients The number of ordered arrangements of n objects, in which there are k1 objects of type 1, k2 objects of type 2, . . . , and km objects of type m and where k1 + k2 + · · ·+ km = n, is ( n k1, k2, . . . , km ) = n! k1! k2! . . . km! . This number is called a multinomial coefficient.
