Question

A box contains different-colored marbles. If P(blue) = 1, P(green) = 4, and P(blue and green) = 12, which state

true?
The events are independent because P(blue). P(green) = P(blue and green).
The events are independent because P(blue). P(green) + P(blue and green).
The events are dependent because P(blue). P(green) = P(blue and green).
The events are dependent because P(blue). P(green) + P(blue and green).

Answer 1

Not 100 percent sure but i think the correct answer is the last one.

Explanation:

I know that the answer is either the last one or before the last because they are dependent on each other. This is because the probability of both increases when they are added together. The more you have the more likely to get one of them. I went for the last one because i think that the value of together is greater than when they are added.

Again, not 100 percent sure, tried to give it my best shot.

Hope this helps.

Answer 2

A) dependent, because the product of P(blue) and P(green) does not equal P(blue and green)
