Probability

In class 12A, 9 students (5 boys and 4 girls) are admitted to a school. School students are randomly divided into 4 classes (each class has more than 9 students). Calculate the probability that in the 4 classes there is one class with 3 male, 2 female class 12A

I'm not going to guess at it.

OP can post the question more clearly if they want it answered.
