There is a jar with 16 marbles. 4 are red, 7 are blue, and 5 are green. You select two marble at random. One marble is drawn and not replaced. Then a second marble is drawn. What is the probability of selecting a red marble and then another red marble?

a. 3/64
b. 1/4
c. 1/20
d. 1/30

I think it’s c, correct me if I’m wrong.

since the marble is not replaced,

P(red,red) = 4/16 * 3/15 = 1/20

you are correct
