How to Use the Multinomial Coefficient Calculator?
 First, input the total number of objects (n).
 Enter the comma or space separated group sizes (k). For example: 2,5,3 or 2 5 3.
 Make sure the sum of group sizes (k) is equal to the total objects (n). If the total number of objects is 12, the group size should be 5,3,4 (5+3+4 = 12).
 Press the 'Calculate' button.
 As a result, the tool computes and shows the multinomial coefficient associated with the given values.
How to Calculate?
The multinomial coefficient is calculated using the following formula:
Multinomial Coefficient = 
n!   (k_{1}! × k_{2}! × ... × k_{j}!)
