For the above to be considered a binomial experiment, it must be guaranteed:

1. That each child must offer one of two answers: yes, if I buy soda (pop) at least once a week / no, I do not buy soda (pop) at least once a week.

2. That the fact that a child, in particular, buys soda (pop) at least once a week, has no relationship (dependence) with another child buying soda (pop) at least once a week. week.
