Permutations and Combinations
So I havea really bad worded question in my opinion... It reads
1a) Given the word leak, calculate the number of permutations:
I wrote 24 because 4! = 24
1b) Calculate the number of 2-letter unordered combinations:
I wrote 6 because 24 / 2 = 12 then half 12 because it's asking for unordered combinations.
2c) By writing out all the permutations and all the 2-letter unordered
combinations, show that the two methods described above give the same result,
and that the number of results are consistent with the numbers you calculated
But they don't give the same result.... one gives 24 and the other 6.... what is it asking for exactly?

I agree this a poorly put question.

I do not understand what 2c) says.
There 24 permutations and 6 combinations.
