Answer :

Answer:

120

Step-by-step explanation:

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

so required number of ways [tex]_{3}C^{10}\textrm{}[/tex]

[tex]_{3}C^{10}\textrm{}=\frac{10!}{3!7!}=\frac{10\times  9\times 8}{3\times 2\times 1}=120[/tex]

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

so the correct answer will be 120
