what are those words??..can you explain why come up of that solution?
Not the answer you are looking for? Search for more explanations.
There are 8 letters. To make words, you put the letters down, one by one.
The first one can be chosen in 8 ways.
The second in 7 ways.
You've got 8*7 =56 possibilities already!
This continues all the way down to the last letter.
So you have 8*7*6*5*4*3*2*1 possibilities.
The mathematical notation for this is 8!
One problem to solve: there are 2 E's so we have counted too much. We have to divide by the number of same possibilities if the two E's are switched. This switching of E's can be done in 2*1 = 2! ways.
End result: 8!/2! = 20160
are you sure of that??
Surprising many, isnt it?
@ZeHanz are you sure??
Sure I'm sure!
If you read carefully what I wrote, you'll come to the same conclusion.
There is no escape.
There are surprisingly many ways to make words with 8 letters...
Of course, most words would be difficult to pronounce and without meaning.
Nevertheless, there are 20160 possibilities,
If you find that hard to grasp, just try with fewer letters:
If you have 1 letter, you can make only one "word".
With 2 letters, the firat one can be chosen from 2, the second has only one possibility.
3 letters: 3*2*1 = 6
4: 4*3*2*1 = 24
It goes up really fast!
