am i wrong?

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.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
