Power BI计算得出的度量值，用于计算列中的三个特定值

Question

I have a table with 500 rows and one of the columns contains a few different values. I want to return a measure that counts the total number of three of the values. So for example, in the pic below, I want to calculate the number of times Ages 11, 12 and 13 appears in the table - which is 7 times. What is the DAX language for this? Thank you

The 'IN' function will do this pretty cleanly. It will let you build a filter that limits your table to the rows whose values match the ones in a list that you supply. Then just count them up.

CountSpecificAges = CALCULATE(
        COUNT (Table1[Age])
        ,  Table1[Age] IN {11, 12, 13}
    )
