ANSWER

2.YES EMPTY SET IS A FINITE SET

• finite set means that we can count the numbers in set.
• empty set means the set which contain 0 element
• so we can count that empty set has 0 element
• 0 is a finite number
• finite number are for ex. all real numbers
• note that 0/0 or any number divided by 0 is not finite.
• null set is denoted by sign fi or { }

3.YES EVERY SET IS A SUBSET OF ITSELF

• subset is that set which contain atleast one element of given set
• for ex let s = {1, 2}
• subset of this set are { }, {1}, {2}, {1, 2}
• thus s is a subset of itself

4.A = {7, 14,.....}

• it contain imfinite numbers among natural numbers so we cannot write it

5.INTERSECTION OF TWO DISJOINT SET IS A NULLSET

• disjoint set meaning no comman element and intersection give element which are comman in both. so there is no vomman element in disjoint sets and it give null set or empty set as result
