Given the digits {1, 2, 3, 4, 5}, how many 3-digit numbers can be formed if: No digit is repeated? (2 marks) P(5,3) = 60 The result must be even, and no digit is repeated? (2 marks) For the final product to be even, there are only 2 options for the final digit (2 or 4), the first digit can any of the remaining 4 digits, and the second digit will only have three other options. 4 x 3 x 2 = 24 The number must contain at least 1 repeated digit?
