Is this independent or dependent ?
Let say you have 10 marbles in the bag. 5 are blue and 5 are red.
First draw: if you want a red marble, you have 5 out of 10 chances to get it.
Second draw: since you dont put the first red marble back, it is not accounted for. So when you reach in the bag, you only have 4 out 9 chances of getting another red marble.
So we can see clearly that the outcome of the 1st draw affects the out come of the 2nd draw; and hence it is dependent
