Answer:
I would say option C.
A and B are not independent events because P(A|B)≠P(A) .
Step-by-step explanation:
We know that: P(A|B) = P(AandB)/P(B)
now, we can plug values that were given.
P(A|B) = 0.15/0.9
P(A|B) = 0.16666
but we have P(A)=0.5
We can see that both are not equal.
P(A|B) ≠ P(A)
So, A and B are not independent.
