NAGALAND Class 11-science Maths Permutations and Combinations
Fundamental Principle of CountingUnderstand fundamental principles of counting Multiplication principle and Addition principle. Solve problems based on these principles.
Permutations: Distinct ObjectsDescribe factorial notation and derive the formula . Permutation of n objects taken r at a time. Problems on permutation of different objects.
Permutations: Non Distinct ObjectsFormulate the theorem of permutation on n objects when all objects are not distinct. Solve problems on arrangements of objects using n!/(P1!P2!...P3!)
CombinationsDerive the formula of combination, differentiate between arrangements and selections. Apply permutation and combination to solve different problems.
Applications of Permutations and CombinationsReview the concepts and theorems of permutation and combinations. Solve problems based on permutations, combinations and both of them.
