Can you answer all questions
The intersection n of two sets is the set of elements which belong to both sets. If you
look at the sets above, then A NB = {ring, earring and cross).
The union of two sets is the set of elements which contains all the elements of both sets.
If you look at the sets above, then AUB= {earring, ring, bangle, cross, chain}.
The complement of a set X, called X', refers to the elements that are part of the
universal set, but which do not fall into set X. So for example, if the universal set was
the set of gold and silver jewellery and set X = [silver jewellery} then set X' = [gold
jewellery}.
Disjoint sets have no common elements. Sets A and C are disjoint.
The universal set is the general set to which a set belongs. The universal set to which
A, B and C belong could be (jewellery).
The number of elements of a set is written as n(A) = 4.
