Have students work on:
1) If you are arranging 3 different Math texbooks, 4 different Science textbooks, and 5 different English textbooks, how many different ways can you organize them if:
a) the books of the same subject must be together?
b) The shelf must start and end with an English book?
c) How many different ways can you pick 2 books from each subject?
2) Explain why 5C2=5C3?
3) Solve: n+1Cn-1=15
4) How much different monetary amounts can you make from 1 penny, 1 dime, 1 quarter, and 1 dollar?
4) Explain everything you know about the expansion of (x+y)^n.
Body:
1) If you know one row of the Pascal's Triangle is
| 1 | 8 | 28 | 56 | 70 | 56 | 28 | 8 | 1 |
2) Determine the last term of the expansion (x-2y)^8.
3) Determine the third term of (a/b-2)^9
4) One term in the expansion of (x+a)^8 is 448x^6, determine the value of a.
5) Determine the constant term in the expansion of (2x-1/x^2)^15
