Total of permutations = 2,520+3*1,680 = 7,560.

## How many different bangles 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 bracelets can be formed from 7 different colored beads?

It would be 7! = 5040 diffrent necklaces. Is that correct?

## How many different bangles can be formed from ten different colored beads?

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 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.

## 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.

## How many necklaces can be made using at least 5 from 8 beads of different Colours?

of necklaces that can be made using at least 5 beads from 8 beads of different colors will be = (8P5)/(2*5) + (8P6)/(2*6) + (8P7)/(2*7) + (8P8)/(2*8). That will be equal to 672 + 1680 + 2880 + 2520 = 7752. The correct answer. This is given in GRE test.

## How many ways can 6 different colored beads be arranged on a bracelet?

= 720 distinct ways (permutations) to arrange the 6 different beads.

## 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 ways can 6 differently Coloured beads be threaded on a string?

Assuming that the beads are different, the first bead can be picked in 6 ways. Then the second bead can be picked in 5 ways. And the third bead can be picked in 4 ways, etc. Multiplying these together, we get 6*5*4*3*2*1 = 720 ways.

## How many ways can 7 beads can be arranged to form a necklace?

2520. 5040.

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

It would be 7! = 5040 diffrent necklaces.

## How many necklaces can be made by using 10 round beads all of a different colors?

This is easy: count all permutations of 10 beads, 10!, then divide by 20 because we counted each permutation 10 times due to rotation, and counted each of these twice because you can flip the necklace over. Thus the answer is 10!/20 = 181440.

## What can you make by stringing Coloured beads together?

Once you get the hang of bead stringing, the creative possibilities for making beading necklaces, bracelets, and anklets are nearly endless.

## What are the number of ways in which 10 beads can be arranged to form a necklace?

Answer: 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.
