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
