Answer:

D. 56%

Step-by-step explanation:

For the fractions we will do:

[tex]\frac{wanted.outcome}{possible.outcomes}[/tex]

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

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

[Dividing] 14 / 25 = 0.56

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

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^∇^)

D because you need to divide and make the quotient into a percent
