Answers
Option (A) is correct.
support(A) ≤ support(B)
Explanation:
If A, B are two sets of items, and A⊆ B. Which of the following statement is always true?: A. support(A) ≤ support(B) B. support(A) ≥ support(B) C. support(A) = support(B) D. support(A) ≠ support(B)If A, B are two sets of items, and A⊆ B. Which of the following statement is always true?:
A. support(A) ≤ support(B)
B. support(A) ≥ support(B)
C. support(A) = support(B)
D. support(A) ≠ support(B)
The true statement is support(A) ≤ support(B)
Given:
It is given that A⊆ B
Solution:
If we have two sets A and B where every element of set A is an element of set B, then A is a subset of B.
A is the subset of B can be written as A ⊆ B or B ⊇ A.
It means the set B is either greater than or equal to set A.
For example:
Set A = {2, 4, 6} and set B = {6, 4, 8, 2}
All elements of A contains in B, so A⊆ B.
Therefore, the correct option is A. support(A) ≤ support(B).
