Combinations - The selection of a number of things taking some or all of them at a time are called combinations. The number of ways of selecting r things out of n dissimilar things is denoted by C(n, r) or n C ..

Permutations and Combinations..

i. In a combination, only selection is made. In a permutation, not only a selection is made, but also there is an arrangement of a definite order. ii. There is no order of selection in combinations. In permutation, order is a must. iii. Usually (i.e., except in special cases or..

, then the number of circular permutations is The selections (groups) of a number of things taking some or all of them at a time are called combinations. The total number of combinations of n distinct things taking r(1 r n) at a time is denoted by n C r or by C(n, r). In particu..

The standard form of the linear programming problem is used to develop the procedure for solving a general programming problem. A general LPP is of the form Max (or min) Z = c 1 x 1 + c 2 x 2 + +c n x n x 1 , x 2 , ....x n are called decision variable..

Linear Programming Problems (LPP) - The standard form of the linear programming problem is used to develop the procedure for solving a general programming problem. A general LPP is of the form Max (or min) Z = c 1 x 1 + c 2 x 2 + +c n x n x 1 , x 2 , ....x n ..
