Answer:
a) 360
b) 60
Explanation:
TAUDRY = 6 letters.
a) The number of 4 letter words that can be formed with 6 letters is 6P4 = 360
b) D _ _ _
D is used, so 5 letters are left to be used. You have to use only 3 of the 5 letters though, so the answer = 5P3 = 60
( btw are there more questions? Because I feel like there are but I can't see any more other than a and b )
