Why in/out

I really can't get how to determine that this was an in/out game. When I did it, I did consider the option but dismiss it because the "passage" just mentions that some out of the 7 parents will be volunteers, so it gives 7 spaces that could be filled, but it NEVER tell us something about having 7 parents and just X (< 7 )number of spots

Hi @Maria-Marin,

We know it’s an in-out game because we know that there are two groups of people: volunteers, and not volunteers. The parents can either be in one group or the other, and there are rules about the parents that say that when one is “in,” another is “out,” and things like this. All of these indicate that it’s a in/out game. Hope this helps!
