What is the sum of all 4-digit numbers that can be formed using the digits 2,2,4,8, no repetition ?

Number of ways the given digits can be re-arranged is 12.

How many times each digit will appear in each place is what I wish to know.
Is there a formula to know this when 2 or more digits are same.
