Practice Discrete Mathematics MCQs for Pakistan exams (CSS, FPSC, PPSC, NTS) — 50 practice questions with answers and explanations.
How to use these questions
Discrete Mathematics on MCQsHub is 50 published questions for Pakistan exams such as CSS, FPSC, PPSC, and NTS. Open a question, choose an option, then read the explanation before you move on. The explanation names the correct choice and why the other options do not fit. Difficulty labels and topic tags show which idea to revise next, instead of repeating questions you already know.
Previous and next links on each question page stay inside Discrete Mathematics, so you can work through the subject without returning to this index. Subtopics listed here belong to the same subject and narrow the set. When you want a clock and a score, start a timed quiz for Discrete Mathematics. When you want a whole sitting rather than one question, open the past-paper library. New Discrete Mathematics questions appear here after editorial review.
The list below starts with the newest Discrete Mathematics questions. Later pages keep the same subject. Each title is a link to the full stem, the options, and the explanation.
The concept in which a set operation that combines all elements from two or more sets into a single set without duplication is best known as which of these terms? Identify the correct definition of Union (set operation). What term describes the following? a set operation that produces a set containing only the elements common to two or more sets. In computer science, Intersection (set operation) refers to which of the following? Select the correct name for: the set of all possible subsets of a given set, including the empty set and the set itself. Which statement correctly explains Power set? Which concept is defined as follows: an operation that produces the set of all ordered pairs formed by combining elements from two sets? What is Cartesian product primarily used for? The following statement describes a specific concept. What is it called? a symbol or word, such as AND, OR, or NOT, used to combine or modify propositions in logic. Select the accurate description of Logical connective. Which term refers to a logical statement that is always true regardless of the truth values of its individual components? What does Tautology refer to? What is the name for a logical statement formed by negating and reversing both the hypothesis and conclusion of a conditional statement?
