Question 433645: 1. A teacher chooses 4 students to attend a seminar. To do this, she chooses one boy and one girl from a class of 14 boys and 12 girls, and one boy and one girl from a class of 13 boys and 13 girls. In how many different ways can the teacher choose the 4 students? (That is, how many different gropus of 4 students can she created if she chooses one student from each of the four listed groups).
Hints:
Assume that the teacher chooses 1 boy from a group of 14, 1 girl from a group of 12, 1 boy from a group of 13 and 1 girl from a group of 13.
So there are 14 choices then 12 choices then 13 choices then 13 choices.
