To state: The numbers of arrangements that is possible for four beads (red, blue, yellow, and green) that are to be arranged on a string to make a simple necklace.
The resultant answer is 6 ways.
Given information:
Four beads (red, blue, yellow, and green) are to be arranged on a string to make a simple necklace.
Explanation:
Total number of beads is 4. Different numbers of arrangements are to be made for these four beads.
In a circle, there is no distinction between the last and first place, only changes in relative position is required.
Therefore, fix one of the four beads in a fix place and then arrange the remaining
Then the value of
Therefore, there are 6 ways in which the 4 beads can be arranged in a string.
