Answer:

To solve this problem, we just have to multiply.

(A) The event: woman in the blue class room is related to 60% of women representation and 30% of students representation in the blue classroom.

Therefore, the chances of choosing a woman student from the blue classroom is


P= 0.60 * 0.30 = 0.18

Which is equivalent to 18% of probability.

(B)

We apply the same process to find the probability of choosing a man from the black classroom.


P= 0.40 * 0.20 = 0.08

Which is equivalent to 8% of probability.

Therefore, there's a 18% of chances of choosing a woman from the blue classroom, and there's a 8% of changes of chossing a man from the black classroom.
