Answer 1

Answer: 792

Explanation:

Given : Hugo and Viviana work in an office with ten other coworkers.

Out of these 12 workers, their boss needs to choose a group of five to work together on a project.

The combination of n thing taking m at a time is given by :-

`C(n;m)=(n!)/(m!(n-m)!)`

Then, the number of different working groups of five the boss can choose :-

`C(12;5)=(12!)/(5!(12-5)!)\\\\=792`

Hence, the number of different working groups of five the boss can choose = 792.
