A 7.7% chance. Hope this helps!

Answer:7/26

Step-by-step explanation:First, find the probability of pulling out a big marble.

Since there are 7 big marbles, and 26 in total,

the probability is 7/26Now, find the probability of pulling out a small marble after the replacement.

There are 6 small marbles and 26 in total, so the probability is 6/26. This can be simplified by dividing each side by 2.

This will get you 3/13To find the probability of both of these happening,

multiply the probabilities by each other:(7/26) x (3/13)

= 7/26

So,

the probability is 7/26
