Answer 2

Answer:

2

Step-by-step explanation:

Look at the picture. That's the probability tree for this question. Since you replace the marble, the second branch will only have 4 outcomes

(4/5)*(3/4)=(3/5)

Look at the second picture. That's what'll happen if you do replace the marble and it'll have 5 outcomes

(4/5)*(4/5)=16/25

If you make the denominators the same, itll be 15/25 if you replace the marble

And 16/25 if you don't replace the marble

Since 16/25 > 15/25, it'll be higher if you don't replace the first marble.
