Probability

If there are 4 red marbles, 7 blue marbles, and 5 green marbles in a jar what is the probability of selecting a red marble, replacing it, and then selecting a blue marble? What is the probability of selecting a red marble, setting it aside, and then selecting a blue marble? 
 
This is from my extra credit tonight, and I cannot figure it out. Can anybody please walk me through it? :)
