Mr. Crosson selects two students from his class to present their reports on Spain. He places the names of each student in a box and picks one at a time. The class has 8 boys and 10 girls. What is the probability that Mr. Crosson will pick two boys in a row if he does not put the first name back in the box? Round your answer to the nearest percent.

For the first student selection, there are 8 boys and 10 girls. The probability of selecting a boy is 8/18 because there are 8 boys in a group of 18.

Assuming that a boy is selected on the first draw, then 7 boys' names remain in the box along with the names of 10 girls. So, the probability of the second boy name is 7/17 because 7 boy names remain in the box in a group of 17.

To get the probability of BB in this scenario, multiply 8/18 * 7/17 and round to the nearest percent.

(C(8,2)*C(10,0))/C(18,2) =
