The least possible number of people in the family is 8.
Step-by-step explanation:
To determine the minimum number of people that make up the family, knowing that 0.83 of the children are boys, the following logical reasoning must be carried out:
Given that 0.83 is the result of 5/6, it can be said that 5 of the 6 children of the couple are boys. These 6 children must be added to the 2 fathers of the family, with which the total number of family members is 8.
