Cartesian product of any two sets is commutative.Group startsTrue or FalseTrue, unselectedFalse, unselected

Composition of two functions is always commutative.Group startsTrue or FalseTrue, unselectedFalse, unselected

The set  F = {(a,x), (b,z), (c,x)}is a function from a set A = {a,b,c} to a set B = {x,y,z}.Group startsTrue or FalseTrue, unselectedFalse, unselected

Cartesian product

Is {Ø, {Ø, {Ø}}∈ C? where C = {Ø, {Ø},{Ø,{Ø}},{Ø, {Ø},{Ø,{Ø}}}}.Group startsTrue or FalseTrue, unselectedFalse, unselected
