How many license plates consist of 2 letters followed by 2 digits, if one of the digits must be odd and the other must be even?

because there are 26 options (since there are 26 letters in the alphabet) for the first and second plates, 5 for the third since there are five odd digits, and five for the fourth since there are also 5 even digits. then multiply by two because the odd and even positions could be switched
