That exhausts the possibilities, so there are 120+300=420 even four digit numbers that can be formed using the digits 0,1,2,3,4,5,6.

How many 4 digit numbers can be formed with the 10 digits 0 1 2 3 9 if a repetitions are allowed B repetitions are not allowed C the last digit must be zero and repetitions are not allowed?

(a)repetitions are allowed, Two ways to get the answer: 1. There are 9999 integers starting with 1 and ending with 9999. But the 999 integers starting with 1 and ending with 999 have less than 4 digits, so the desired number is 9999-999 or 9000 ways.

How many numbers can be formed from the digits 1 2 3 9 if repetition of digits is not allowed?

But we cannot take any of the 4 digits given in the second place because repetition is not allowed here. So, we have 3 intakes for second place. Similarly, for the 3rd place, we have to choose any one digit of the remaining two digits and proceed with 1 intake for the 4th place. Hence, 64 numbers can be formed.
