In how many ways can a member of a hiring committee select 3 of 12 job applicants for further consideration?

220

Step-by-step explanation:

When we wanto to create a group of K elements for a set of N elements (where the order of the K elements does not matter, so we do not considerate the permutations of the K elements), the number of possible combinations is:

Here N = 12 and K = 3

So there are 220 possible combinations

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
