Question

During the Computer Daze special promotion, a customer purchasing a computer and printer is given a choice of three free software packages. There are 10 different software packages from which to select. How many different groups of software packages can be selected?

Answer 1

Answer:

120

Step-by-step explanation:

Here there are 10 different packages in which we have to choose 3

so required number of ways $_{3}C^{10}\textrm{}$

$_{3}C^{10}\textrm{}=\frac{10!}{3!7!}=\frac{10\times 9\times 8}{3\times 2\times 1}=120$

So there are 120 ways in which we select the different groups of software package.

so the correct answer will be 120
