Step 1
To construct a 4 digit number consisting of distinct digits we have 9 ways to choose the first digit (we can't pick 0), 9 ways to choose the second (we can't repeat the first) then 8 and 7 ways to choose the last two without repetition. Using the multiplication rule, we find that there are ( 9 ) ( 9 ) ( 8 ) ( 7 ) = 4536 numbers in the list that have distinct digits.
Step 2
y = 453 , a n d   z = 6
