Mr. Rosart selects two students from his class to present their book reports. He places the names of each student in a box and r
andomly picks one at a time. The class has 15 boys and 11 girls. What is the probability that the second name Mr. Rosart picks is a boy, if the first one is a boy also? Round your answer to the nearest percent. A. 54%
B. 44%
C. 60%
D. 56%
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]
[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^∇^)
To subtract integers, change the sign on the integer that is to be subtracted. If both signs are positive, the answer will be positive. If both signs are negative, the answer will be negative.
