The contents of a jar holds 4 red marbles, 7 blue marbles, and 5 green marbles from which you select marbles at random.
What is the probability of selecting a red marble, replacing it, and then selecting a blue marble? Show your your work.
Is it 4/16 for picking red then 7/16 for picking blue?
What is the probability of selecting a red marble, setting it aside, and then selecting a blue marble? Show your work.
Is it 4/16 for red then seeing it aside and picking blue 7/15?
Are the answers to parts (a) and (b) the same? Why our why not?
I would say no because there are two different probabilities. Am I correct on all three answers, if not please help.
