Question

the number of permutation of letters abc is 6​

Answer 1

Answer:

Think of the letters ABC as glued together. Thus we really have six objects, namely, the super letter ABC, and the individual letters D, E, F, G, and H. Because these six objects can occur in any order, there are 6! = 720 permutations of the letters ABCDEFGH in which ABC occurs as a block.

Step-by-step explanation:

So the first five letters can be a combination of 6x5x4×3×2 letters or 720 arrangements. The final letter can now be only 1 letter because all of the others have been used. So the six letters can be a combination of 6x5x4x3x2x1 letters or 720 arrangements.

sorry if wrong:))
