Answer: There are 252 different working groups of five that can be formed.

Step-by-step explanation:

Since we have given that

Number of workers = 12

Number of group of people to work together on a project = 5

Since Hugo and Viviana absolutely refuse, under any circumstances, to work together.

So, remaining number of workers = 12-2=10

so, we need to find the number of different groups of five that can be formed.

We will use "Combination":

$^{10}C_5\\\\=252$

Hence, there are 252 different working groups of five that can be formed.
