Count Random Object in region

Hello everyone!

Could you please help me to solve the following problem?

I'm creating a division game for Primary school students, they are going to drag some objects into the region according to the formula Div(x,y).

For example



Div (20,4)

then the student has to drag 5 random objects into the region.

Someone suggested me to use the IsInRegion Command, however, it only counts specific object but not random object.

Thank you for your help!

create a list L with all random objects

then use length(keepif(isinregion(P,<nameofregion>),P,L))
