You can put this solution on YOUR website!
What you are showing is what is called a permutation.
Permutations (and combinations) are used in probability and statistics to find certain numbers.
For example, the number of ways a group of 5 books can be arranged on a shelf.
Permutations are order-specific, while combinations are not order-specific.
A good example of a permutation is the Cash 3 lottery,
while a good example of a combination is the regular lottery where the numbers can appear in any order.
The formula for a permutation is:
In this case, your n is equal to 6, and your k is equal to 0.
What they are asking then,
is how you can arrange 6 items 0 at a time (or in groups of 0).
Of course this sounds illogical, but there is only 1 way to do so.
And if you put your numbers into your formula, you will get an answer of 1.
Take it step by step, try some different numbers in the formula, and see how it goes.
Reread your book, and if you still have questions don't be afraid to post them.
I hope this helps! :)
