In this problem, we are given the digits and they are 0, 1, 2, and 3.
00:08
And we have to determine the number of different four digit, even numbers that we can form using these digits.
00:19
So we will consider that to be represented by n, and that's what we have to get here.
00:24
So first we count and we see that there are in total four number of digits which are given to us.
00:29
And out of these four digits, we have two even digits, which are zero and two.
00:35
So we will consider four different boxes here, where each box represents a digit in a four -digit even number.
00:42
And we know that a four -digit even number will have the last digit, which is even -digit.
00:49
So we will have two possibilities here.
00:52
The last is filled with zero.
00:55
So that means we will have one way to do this...
