Answer:

D. 56%

Step-by-step explanation:

For the fractions we will do:

\frac{wanted.outcome}{possible.outcomes}

      It depends on if he puts the first name back in, but I am going to asume Mr. Rosart does not, <em>so we will subtract one from the boys for the second pull</em>.

[Wanted over possible] \frac{14}{25}

[Dividing] 14 / 25 = 0.56

[Making a percent] .56 * 100 = 56%

<u />

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
