Assume you have a small bag full of marbles, 45 are red, 25 green, and 30 yellow. Suppose you don’t like the red ones and every time you pick red you put it back in the bag. If you pick green and yellow you keep it. Assume you only take one marble at the time (not looking) and randomly select 3 times. What is the probability of; a)You will have exactly one marble? b)You will have at least 2 marbles? c)You won’t have any marbles?
