Question

The binomial coefficient Subscript n Baseline Upper C Subscript x gives the number of ways of picking a subset of x items out of n. Using this​ fact, how many ways are there to pick a committee of 4 from among all of the office​ employees?

Answer 1

Answer:

${n \choose 4}$ where n s the total number of employees

Step-by-step explanation:

Since ${n \choose x}$ gives the number of ways you can pick a subset of x elements from n.

remember in order to calculate the combination number ( for example if you know the number of office employees) is

${n \choose 4}=\frac{n!}{4! (n-4)!}$

using that 4! =1*2*3*4  and same idea for n!
