There are two possible digits for the first and last digit, and two possible digits for the centre digit, making 2 × 2 = 4 possible 3 digit palindromes from the set {1, 2}, namely the set {111, 121, 212, 222}.
3000 and 6000 both have 3 0's, so they are out. The numbers between them all start with 3, 4, or 5, followed by 3 digits. There are 9 possible digits for the hundreds place, which leaves 8 for the tens and 7 for the units digit. The answer is therefore 3 x 9 x 8 x 7 = 1512 Answer 1 ======= There are 4 possible first digits, 9 possible second digits, 8 possible third digits and 7 possible 4 digits, making a total of 4 x 9 x 8 x 7 = 2016.
A 9-digit credit card code typically refers to the Card Verification Value (CVV) or similar security code that some card issuers use for online transactions, but most commonly, CVVs are 3 to 4 digits long. If you're referring to something else, such as a specific banking or account identifier, please clarify. Generally, for credit cards, the standard format includes 16 digits for the card number, and CVV codes are separate for security verification.
