So here i am again, yes with another retarde post in most of your eyes but I come here because I need help
Here is the question.
Consider the name "john smith" with j letters for the first name and k letters for the second name and where the space between the name is not part of the name. Give a formula for the number of permutations if the first and second names are permutated independently
How is the formula written to explain this question?
