Question

find the number of garlands made by 6 distinct beads

Answer 1

Answer:

Good Luck :)

Step-by-step explanation:

Look either you can go by:-

Select any bead first- no of ways:6C1

Then arrange the others now because the symmetry is broken-no of ways:5!

But after writing this u will find that the same structure would be repeated because of the circular arrangement when u take another beads as starting point as thus forms a circular arrangement and thus it never end. It is a continuous arrangement

Thus every structure is repeated 6 times, then divide throughout by 6

The Ans is: 6x5!/5= 5!

         OR

Another method for all such garland sums are (n-1)! Ehich is always valid for any of the circular arrangement

Answer 2

Answer:

Step-by-step explanation:
