Question

O.T.BA
Set theory is a branch of mathematics that is conced with groups of objects and numbers known as sets. Sets theory deals with the propertics of these
sets as single units, regardless of the nature of the individual elements within the set.
A SET is a collection of objects and each them in the set is called an Element. Even though most sets do contain at least one element, there are special cases
when a set contain No elements. A set containing exactly zero elements is called empty set.
We can further define certain elements within a set to be in a subset which is smaller set of elements taken from within set. If we combine these two sets, this
is called union. Noticing that repetition should not be there The Intersection of the two sets contains only those elements that are found in both and disjoint sets are
sets that do not have any elements in common. The intersection of two disjoint sets would be an empty set which is denoted by .
Answer the following questions:
Let A = {all odd numbers less than equal to 25}
B = {all prime numbers less than equal to 25)
