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

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

Let A denote the lower-case English alphabet {a, b, c, . . . , z} and let X = A × Z × A × (Q ∖ Z). Use set-roster notation to give an example of a subset of X that has exactly five elements.

If A = {1, 2, 3, 4, 5} , B = {a, b, c, d, e} and C = { -, +, x, @, *} , then which of the following is the not the element of set (A x B x C)?{1,a,#}{4,b,+}{5,a,@}{1,e,*
