Answer:

The correct option is:

d

Yes, P(Female ∩ Blue) = P(Female) ⋅ P(Blue)

Explanation:

Two events are dependent where happen together. In this case, blue happens without female happens (there are males that choose blue), thus they're independent events

The formula for two independent events is:

P(A ∩ B) = P(A) · P(B)
