    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 7/26

    Now, 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 3/13

    To 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
