List out some sets A and B and choose their elements such that A and B are disjoint.

Write some sets A and B such that A and B are disjoint.

Two sets A and B are said to be disjoint if

If a set A has 5 elements , then the number of ways of selecting two subsets P and Q from A such that P and Q are mutually disjoint is

If in two sets A and B , every element if A is in B and every element of B is in A. then we write it as………..

List out some food items and mention the ingredients required to prepare them in the table given below

A set A has 3 elements and another set B has 6 elements. Then

If A and B are two disjoint events such that P(A) = 2/7 , P(B)=3/5 then P(A or B) =
