Hi everybody, can someone please help with this?

By a graph we shall here understand the graph of a function in $\displaystyle [0,1]^{[0,1]}$. The paving in [0, 1] × [0, 1] = $\displaystyle [0,1]^2$of all graphs is denoted G. By a full set we shall here understand a subset A $\displaystyle \in$ [0, 1] × [0, 1] with full projection on the first axes in the sense that for every x $\displaystyle \in$[0, 1] there exists y $\displaystyle \in$[0, 1] such that (x, y) $\displaystyle \in$A. The paving in [0, 1] × [0, 1] of all full sets is denoted F.

Determine the cardinalities of the sets G and F. Show that no set in G can intersect every set in F.

I think that the answer to that about G is either $\displaystyle \aleph_0$ or $\displaystyle 2^{2^{\aleph_0}}$, the last one being the cardinality of all real valued functions on real numbers:
