Client buys multiple category product and I need to calculate the count of customer who purchased only type1 and type2 together minus the result of when these category are bought together along with third category

Hi @Anonymous 

You can refer to the following measure, the sample data is the same as yours

Measure =
VAR a =
    CALCULATETABLE (
        DISTINCT ( 'Table'[Customer_id] ),
        'Table'[Product_category] IN { 1, 2 }
    )
VAR b =
    CALCULATETABLE (
        DISTINCT ( 'Table'[Customer_id] ),
        'Table'[Product_category] = 3
    )
RETURN
    COUNTROWS ( EXCEPT ( a, b ) )

Output
