Answer:
This test batch can be chosen in 2380 ways
Step-by-step explanation:
The order in which the batteries are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
In how many ways can this test batch be chosen?
4 batteries from a set of 17. So
![C_{17,4} = \frac{17!}{4!(17-4)!} = 2380](https://tex.z-dn.net/?f=C_%7B17%2C4%7D%20%3D%20%5Cfrac%7B17%21%7D%7B4%21%2817-4%29%21%7D%20%3D%202380)
This test batch can be chosen in 2380 ways
