## How many ways can 8 differently Coloured beads be threaded on a string?

**2520 Ways** 8 beads of different colours be strung as a necklace if can be wear from both side.

## How many necklaces can you make with 10 beads of 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**.

## How many ways can 12 beads be arranged on a bracket?

12 different beads can be arranged among themselves in a circular order in **(12-1)!=** **11!** **Ways**. Now, in the case of necklace, there is not distinction between clockwise and anti-clockwise arrangements.

## How many different necklaces can be formed using 9 different Coloured beads?

This leaves us with 18,150 – 6 = 18,144 strings. The total number of necklaces we can form with these strings is 18,144 ÷ 9 = **2016**.

## How many different ways can the 8 persons be seated in a circular table?

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

## How many ways can a person choose 1 or more of 4 electrical appliances?

Total ways is **15**.

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

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

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

2520. **5040**.

## How many ways 10 beads can be arranged?

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**.

## How many ways can 5 people arrange themselves in a line?

Answer: If the symmetry of the table is not taken into account the number of possibilities is 5! = **120**. In this case it would be the same as ordering people on a line. However if rotation symmetry is taken into account, there are five ways for people to sit at the table which are just rotations of each other.

## How many necklace of 12 beads each can be made from 18 beads of different 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 beads be arranged in a string?

6P6 = **720** or 6!

## How do you find the permutation of a word?

To calculate the amount of permutations of a word, this is as simple as evaluating **n!** , where n is the amount of letters. A 6-letter word has 6! =6⋅5⋅4⋅3⋅2⋅1=720 different permutations. To write out all the permutations is usually either very difficult, or a very long task.

## 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** .
