DAX measure to filter for multiple values in one column and one value in a second column

[Anonymous]

I am having trouble coming up with a measure to count the number of students who have attended a set of subjects in the below data table. For example, if I wanted to count the number of students who have attended all Calculus, History, and Writing subjects, I would want the measure to output only Charles, as  he is the only student has met this criteria. I came up with the following: 

AllTopics = COUNTROWS(FILTER('Table1',('Table1'[Subject] = "Calculus" || 'Table1'[Subject] = "History" || 'Table1'[Subject] = "Writing") && 'Table1'[Present] = "Yes")).

Subject	Present	Student
Physics	Yes	Charles
Physics	Yes	Daryl
Physics	Yes	John
Physics	Yes	Jess
Calculus	Yes	Daryl
Calculus	Yes	Charles
Calculus	Yes	Charles
Calculus	Yes	Charles
Calculus	Yes	Henry
Calculus	Yes	Jess
Calculus	Yes	Charles
Calculus	Yes	Charles
History	Yes	Lucas
History	Yes	Charles
History	Yes	Edgar
History	Yes	Charles
History	Yes	Charles
History	Yes	Edgar
History	Yes	Edgar
History	Yes	Charles
History	Yes	Tess
Calculus	No	Charles
History	No	Lucas
History	No	Charles
History	No	Edgar
History	No	Charles
History	No	Charles
History	No	Edgar
History	No	Edgar
History	No	Charles
History	No	Tess
History	No	Edgar
Writing	No	Daryl
Writing	No	Edgar
Writing	No	Tess
Writing	No	Tess
Writing	No	Edgar
Writing	Yes	Tess
Writing	Yes	Charles
Writing	Yes	Edgar
Writing	Yes	Edgar

Hi @Anonymous 

Please use the measure below:

Measure 2 = 
VAR PassStudent =
    FILTER (
        SUMMARIZE (
            CALCULATETABLE ( 'Table1', ALL ( 'Table1'[Subject] ) ),
            Table1[Student],
            "AllPass", IF (
                CALCULATE (
                    COUNTROWS ( DISTINCT ( 'Table1' ) ),
                    FILTER (
                        'Table1',
                        'Table1'[Present] = "Yes"
                            && 'Table1'[Subject] IN { "Calculus", "History", "Writing" }
                    )
                ) >= 3,
                1,
                0
            )
        ),
        [AllPass] = 1
    )
RETURN
    IF (
        CALCULATE (
            COUNTROWS ( 'Table1' ),
            FILTER (
                'Table1',
                'Table1'[Present] = "Yes"
                    && 'Table1'[Subject] IN { "Calculus", "History", "Writing" }
            )
        ) > 0,
        CALCULATE (
            DISTINCTCOUNT ( 'Table1'[Student] ),
            FILTER (
                'Table1',
                'Table1'[Student] IN SELECTCOLUMNS ( PassStudent, "Student", 'Table1'[Student] ) && 'Table1'[Subject] IN { "Calculus", "History", "Writing" } && 
                'Table1'[Present] = "Yes"
            )
        ),
        BLANK ()
    )

Try

CALCULATE(COUNTX(filter(SUMMARIZE(Student,"s1",COUNTROWS(FILTER('Table1',('Table1'[Subject] = "Calculus" || 'Table1'[Subject] = "History" || 'Table1'[Subject] = "Writing") && 'Table1'[Present] = "Yes"))),[s1]>=3),[s1]))
