I wanna do the even questions for the chapter

2,3,4,5,6,7,8,9,12,13,14. Also concept map is required for each chapter. Let's start with chapter 2 and 3 to see them with my instructor if them are perfect we are gonna do the rest. Here is a link that describes concept maps and how to build them:

Also here is an example of how an exercise solution should be presented:

Mrs. Steffen's third grade class has 30 students in it. The students are divided into three groups (numbered 1, 2, and 3 ), each having 10 students.

a. The students in group 1 earned 10 extra minutes of recess by winning a class competition. Before going out for their extra recess time, they form a single file line. In how many ways can they line up?

Solution.

There are 10 students in group 1. All students must line up but they can do so in any order. It follows that the number of ways these 10 students can line up is , where . Thus we have:

Intuitively, the above answer makes sense as there are 10 choices of student to be first in line, 9 choices for second in line, eight choices for third in line and so on until we have a single choice for last in line.

In conclusion, the number of ways these 10 students can line up is equal to

You should explain each of your solutions as I have done in the example above. Thanks
