If S = {a, b, c}, Then the power set of S  is P(S) =  { ∅, a, b, c, {a,b}, {a,c}, {b,c}, {a, b, c} }Group startsTrue or FalseTrue, unselectedFalse, unselected

Consider A={a} then ,  the power set of a set A ={Φ,{a}}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

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

If S = {Φ, {a}, {b}, {a, b}, {b, a}, {a, b, c}, {c, a, b}}, then the cardinality of S  is 5.Group startsTrue or FalseTrue, unselectedFalse, unselected

The set R = {(a, l), (2, b), (c,3)} is a relation from A = {a, b, c, d} to B = {1, 2, 3}. Group startsTrue or FalseTrue, unselectedFalse, unselected
