    Answer:

    If we are choosing students at random from all students who got a B:

    Total number of non-female students who got a B: 19

    Total number of students who got a B: 36

    Probability: 19/36

    If we are choosing students at random from all students:

    Total number of non-female students who got a B: 19

    Total number of students: 78

    Probability: 19/78
