An art teacher wrote the expression [(240 divided by 6) + (120 divided by 6)] to determine how many sheets of red paper and sheets of blue paper to put at each table in her classroom. Which could be the total number of red sheets and blue sheets of paper she put on each table?

Aclassroom is made up of 11 boys and 14 girls. the teacher has four main classroom responsibilities that she wants to hand out to four different students (one for each of the four students). if the teacher chooses 4 of the students at random, then what is the probability that the four students chosen to complete the responsibilities will be all boys?
