What is the independent and dependent event for pulling two marbles out of a bag?

Bill has a bag of marbles If he knows that his bag contains 2 blue 3 red and 4 clear marbles what are the odds for Bill choosing a clear marble or a blue marble if he pulls one marble from the bag?
2/3rd is the answer This is a case of probability, the probability of getting only blue marble is 2/9 and only clear marble is 4/9, since we are looking for either of blue or clear, we will add the probabilities and upon adding these two it is 6/9 which translates into 2/3rd.
