Download the latest multi choice Question and answer about Permutation and Combination Problems for PPSC, FPSC, NTS, PMS, CSS, SPSC, and KPKPSC exam
Permutation and Combination MCQs are common type of question that appears in many competitive exams. These questions test your understanding of the concepts of permutation and combination, which are important for quantitative aptitude.
- Permutation: A permutation is the arrangement of a set of objects in a specific order. For example, the arrangement of the letters "ABCD" is a permutation.
- Combination: A combination is a selection of a subset of objects from a larger set. For example, the selection of the letters "AB" from the set "ABCD" is a combination.
Here are some examples of permutation and combination MCQs:
- A group of 5 students is to be arranged in a row. In how many ways can this be done?
- A committee of 3 people is to be selected from a group of 5 people. In how many ways can this be done?
- A bag contains 3 red balls, 2 blue balls, and 1 green ball. In how many ways can 2 balls be selected from the bag?
These are just a few examples of permutation and combination MCQs. There are many more types of permutation and combination problems that can appear in competitive exams. By practicing regularly, you can improve your ability to solve permutation and combination problems and increase your chances of success in these exams.
Here are some additional tips for solving permutation and combination problems:
- Use the permutation formula: The permutation formula is used to calculate the number of permutations of a set of objects. The formula is:
where n is the number of objects in the set and r is the number of objects that are being arranged.
- Use the combination formula: The combination formula is used to calculate the number of combinations of a set of objects. The formula is:
nCn = 1
nC1 = n
nC2 = n(n - 1) / 2
where n is the number of objects in the set and r is the number of objects that are being selected.
- Remember that order matters in permutations, but not in combinations: This is an important distinction to keep in mind when solving permutation and combination problems.
- Practice, practice, practice!: The best way to improve your ability to solve permutation and combination problems is to practice regularly. There are many other file on Permutation and Combination MCQs available that can help you with this.
