if the set u = {all positive integers} and set a = {x|x ∈ u and x is an odd positive integer}, which describes the complement of set a, a^c?\n\na^c = {x|x ∈ u and is a negative integer}\na^c = {x|x ∈ u and is zero}\na^c = {x|x ∈ u and is not an integer}\na^c = {x|x ∈ u and is an even positive integer}
Answer
Explanation:
Step1: Recall complement definition
The complement of a set A, denoted as (A^{c}), contains all elements in the universal set U that are not in A.
Step2: Identify elements in U and A
The universal set U is all positive integers. Set A is all odd positive integers.
Step3: Determine (A^{c})
The elements in U that are not in A are the even positive integers.
Answer:
D. ({x|x\in U \text{ and is an even positive integer}})
