NCERT Solutions for Class 11 Maths Exercise 7.1: Points to Remember

Some of the important points to remember from Class 11 Maths Exercise 7.1 are as follows:

Formula of Permutations: ⁿP_r = n!/(n−r)!
Formula of Combinations: ⁿC_r = n! / [r! * (n−r)!]
The permutation formulas is justified as P_r = n!/(n-r)! ; 0 ≤ r ≤ n
The notation used to express the permutation is “n Pr” if the number of permutations of n different items taken r at a time will meet the requirement 0 r n and the objects which do not repeat are n (n – 1) (n – 2)……(n – r + 1).
The formula n! / p! is used to calculate the number of permutations of the objects when ‘n’ and ‘p’s are of the same sort and the remainder are all different.
