Counting TYPES of duplicates

I have a dataset that has a good number of duplicates, many of which have more than 2 records.

In these sets of duplicates, there are two fields that have many combinations of values.

I would like to find a way to COUNT THE COMBINATIONS in all of the sets of duplicates, as in, every time there is a type of a certain combination of values, create a count for it:

12345 9 9
12345 9 0

123456 9 9
123456 9 0

(Total: 2) For 9/9 and 9/0

12344567 0 0
12344567 0 0
12344567 0 0

12344567 0 0
12344567 0 0
12344567 0 0

(Total: 2) For 0/0 3x

I have attached a listing of types of combinations that I found by scanning the database, but I don't know what formula or functions would do the trick. I don't think there is something in Subtotal or the Count functionalities that would apply but I will fumble around.

Any help would be appreciated.
