Digits: 1, 2, 3, 4, 5
Q: how many even 3 digit numbers can be made without repeating them?
In total, I worked out that there's 60 three digit numbers that can be made without repeating (5C1 x 4C1 x 3C1) = 60.
But, I have no idea about the even bit. Could somebody talk me through it so I can understand?
