9. The supervisor of a call center would like to assemble a committee of 8 people from a staff of 15 call center agents
How many different committees can be chosen?
1. 120
2. 6,435
3. 32,432,400 4.259,459,200

Number of different committees that can be chosen = 6435

So,option 2 is correct

Step-by-step explanation:

The supervisor wants to assemble a committee of 8 people from a staff of 15 call center agents.

To solve this we will make use of the combination formula which is:

C(n, r) = n!/[r!(n - r)!]

Where n is population (or available number of people who can sit on the committee) and k, the number selected)

In this question, n = 15 and r = 8

So, we have;

C(15,8) = 15!/[8!(15 - 8)!]

This gives;

C(15,8) = 15!/(8! × 7!)

C(15,8) = 1307674368000/(40320 × 5040) = 6435

Number of different committees that can be chosen = 6435

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
