Question

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.

Answer 1

The probability of the first student being a boy is 8/18 (boys/total students).
The probability of the second one being a boy is then 7/17.
multiply the two probabilities.
0.4444*0.4118=0.183 or 18%
