The diagram shows the contents of a jar of marbles. You select 2 marbles at random. One marble is drawn and returned. Then the second marble is drawn. What is the probability of selecting a blue marble and then a green marble? A.7/16
B.35/256
C.7/48
D.1/20

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
