新 GRE 数学重要考点：并集和交集攻克新 GRE 数学的重要学问点，今日我为大家带来的是有关 Intersection of Sets 的相关内容
Intersection of Sets Intersection of two sets is another set with only the members that are in both sets
If the two sets do not share any common member, the intersection is the empty set with no member
Example: Intersection of {1,2,3} and {2,3,5} is the set {2,3}
Intersection of the set with all primes and the set with all even numbers is the set {2} since only 2 is both even and prime
Intersection of {1,2,3} and {4,5,6} is the empty set {}
Remember: Intersection contains only the common members
Two sets are disjoint if they have no member in common, that is they have an empty intersection
Union of Sets Union of two sets is another set with all the members from both sets
Example: Union of {2,3,5} and {1,3,4
