How many possible combination of 7336?

Answer 1

To find the number of possible combinations of the digits in the number 7336, we need to consider the arrangement of the digits while accounting for the repeating digit '3'. The formula for permutations of a multiset is given by ( \frac{n!}{n_1! \times n_2! \times ...} ), where ( n ) is the total number of items and ( n_1, n_2, ) etc., are the frequencies of the repeating items. Here, the total number of digits is 4 (7, 3, 3, 6), so the calculation is ( \frac{4!}{2!} = \frac{24}{2} = 12 ). Thus, there are 12 unique combinations of the digits in 7336.
