If R is the set of real numbers and Q is the set of rational numbers, then what is R – Q ? . State whether each of the following statement is true or false. Justify your answer.
{ , , , } and { , } are disjoint sets. { a, e, i, o, u } and { a, b, c, d }are disjoint sets. (iii) { , , , } and { , , , } are disjoint sets. (iv) { , , } and { , , } are disjoint sets.
. Complement of a Set Let U be the universal set which consists of all prime numbers and A be the subset of U which consists of all those prime numbers that are not divisors of . Thus, A = { x : x ∈ U and x is not a divisor of }. We see that ∈ U but
