Random objects through grid points

Hello guys, I'm trying to create a grid and put two different objects in it.
The object 1 in some points and the object 2 in the others.

The problem is that i don't know how to randomize these objects through the grid points. They are only in rows (Figure 01) and when I try to use the RANDOM function, it generates the error "impossible to convert number to points". (Figure 02)
How can I fix this?
Thank you for your help!

    Hi.

    You'll need boolean pattern which has the same data tree structure as your grid points.
