You can put this solution on YOUR website! From the digits 9,8,6,5,4,1 how many 3 digit even numbers can be formed,
without repetition of digits?
Choose the third (units) digit 3 ways (8,6 or 4)
That leaves 5 ways to choose the 1st (hundreds) digit.
That leaves 4 ways to choose the middle (tens) digit.
Answer 3 = 60 even three digit numbers from 9,8,6,5,4,1
without repetition of digits.
