If A-B={ }
Then prove that A is a subset of B
Answers
Answer:
Empty set
Step-by-step explanation:
or null or { } or phi
(A - B : Elements of set A, which are not elements of set B). A is subset of B, means set B contains all elements of set A plus may have some additional elements. Example A= {1,2,3}
B={1,2,3,4,5}. A is subset of B. To find A-B, consider set A elements 1,2,3 & then cut (minus) the elements of set B. So all elements 1,2,3 are cut & A-B is the null set. Set without having any element.
Answer:. A - B = { }
