Hello, Johnboe!

1) How many 6-letter subsets can you make if 2 are consonants and 4 are vowels"

The problem is not clearly stated.

It says, so the order of the letters is not considered.subsets

If letters maybe repeated in the subsets,not

. . there are: . choices for the consonants

. . and choices for the vowels.

There are: . possible subsets.

If letters may be repeated, it is a very messy problem . . .
