## How many necklaces can be formed with 8 beads?

The number of ways in which 8 different beads be strung on a necklace is. **2500**. 2520.

## How many different angles can be formed from 8 different colored beads?

How many different bangles can be formed from 8 different colored beads? Answer: **5,040 bangles** .

## How many ways can 9 different colored beads be arranged on a necklace?

This is called a cyclic permutation. The formula for this is simply (n-1)!/2, since all the beads are identical. Hence, the answer is 9!/2 = 362880/2 = **181440**.

## How many arrangements of beads are possible in a bracelet if there are 6 different designs of beads?

Since there are 6! linear arrangements of six distinct beads, the number of distinguishable circular arrangements is 6! 6=**5**!

## How many necklaces can be formed 7 distinct beads?

It would be 7! = **5040 diffrent necklaces**.

## How many necklaces of 12 beads each can be made from 18 beads of various Colours?

Correct Option: C

First, we can select 12 beads out of 18 beads in ^{18}C_{12} ways. Now, these 12 beads can make a necklace in **11! / 2** ways as clockwise and anti-clockwise arrangements are same. So, required number of ways = [ ^{18}C_{12} . 11! ] / 2!

## How many bracelets can be made by stringing 9 different colored beads together?

by stringing together 9 different coloured beads one can make **9!** **(9 factorial )** bracelet. 9! = 9×8×7×6×5×4×3×2×1 = 362880 ways.

## What is the number of necklaces that can be made from 20 beads each of different Colour?

Thus the answer is **10**!/20 = 181440.

## How many different bangles are there?

There are **two basic types of bangles**: a solid cylinder type; and a split, cylindrical spring opening/closing type. The primary distinguishing factor between these is the material used to make the bangles. This may vary from anything from glass to jade to metal to lac and even rubber or plastic.

## How many ways 5 beads are used to make a necklace?

One is clockwise, another is anticlockwise. Here in both directions we will get the same arrangement. So, we have to divide 24 by 2. Therefore the total number of different ways of arranging 5 beads is 242=**12** .

## How many ways can the 7 persons be seated in a circular table?

Complete step-by-step answer:

Since in this question we have to arrange persons in a circle and 7 persons have to be arranged in a circle so that every person shall not have the same neighbor. Hence there are **360 ways** to do the above arrangement and therefore the correct option is A.

## How many ways can 8 people be seated around a circular table if two of them insist on sitting beside each other?

ways, where n refers to the number of elements to be arranged. = **5040 ways**.

## How many ways can you arrange things in a circle?

Coming back to the question – In how many ways can 5 distinct objects be arranged in a circle? Now there are 5! or **120 different linear arrangements possible**.

## What is restricted permutation?

A Restricted permutation is **a special type of permutation in which certain types of objects or data are always included or excluded and if they can come together or always stay apart**. (a)Number of permutations of ‘n’ things, taken ‘r’ at a time, when a particular thing is to be always included in each arrangement.
