Please answer
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.

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
