### Annotations 4

1. 1. Annotations 4 Classroom
2. 2. Question 4 a.) <ul><li>Since order matters in this problem (once a student is seated, another student cannot sit in the same desk) we use the “pick” formula. The variable “n” represents the number of objects to pick from (in this case 16 desks) and the variable “r” represents the number of objects to be arranged (13 students) </li></ul><ul><li>Simplifying occurs and we find our answer by punching this term into our calculators. </li></ul><ul><li>Our answer is rounded to 4 decimal places. Since this is a word problem, always answer in a full sentence. </li></ul>
3. 3. Question 4 b.) Slide 1 <ul><li>In a room with 16 chairs arranged in a 4x4 pattern, there are 16 total ways to arrange two people side by side in the same row. </li></ul><ul><li>Also, there are 2! Ways to arrange the two students next to each other (Oliver, Lilly or Lilly, Oliver). </li></ul>
4. 4. Question 4 b.) Slide 2 <ul><li>Out of 16 possible ways to arrange the two students, we choose 1 by applying the “choose” formula. Next, we multiply that number by 2! Ways to arrange the two students side by side. Finally, we multiply that number by 14 Pick 11 (There are 14 desks available and 11 students left to be seated) </li></ul><ul><li>After calculating the solution, we incorporate our answer into a full sentence. </li></ul>
5. 5. Question 4 c.) <ul><li>Since we know the number of ways to arrange the 13 students (without restrictions) in 16 desks is 3.4871x10^12 and we know the number of ways two students can be seated together side by side in the same row is 464950886400, to find the number of ways they are not seated together we simply subtract. </li></ul><ul><li>Again our solution is rounded to 4 decimal places and incorporated in a full sentence. </li></ul>
6. 6. Question 4 d.) <ul><li>This question is easier than it sounds since we already have two important sets of information that we require. </li></ul><ul><li>Simply put, we divide the amount of ways possible to arrange the 13 students with John and Richard seated side by side in the same row (464950886400) by the number of ways to arrange the students without restrictions (3.4871x10^12). </li></ul><ul><li>Our answer will be a percentage because the question is asking for a probability. Lastly, our answer is incorporated in a full sentence. </li></ul>
