1. 1.

2. 2, Binomial coefficients are related to the pascal's triangle as they refer to an specific point on the nth row, and. rth element of the triangle.

3. 3. nCr means when you want to select r things from n different options.

4. 4. Some different ways to write nCr are

5. 5. nPr means the number of ways in which you can pick r things from n different options and arrange them.

6. 6.nC0 equals 1, and nC1 equals n.

7. 7. The formula for nCr is ^nCr =n!/r!(n-r)!

8. 8. nCr is equal to nC(n-r), we can prove this by replacing "r" with "n-r" and simplifying the equation.
