A deck of playing cards consists of 52 cards divided into 4 "suits": hearts, clubs, spades, and diamonds. Each suit consists of 13 cards with different values: 9 "number" cards (numbered 2, 3, 4, 5, 6, 7, 8, 9, and 10), 3 "face" cards (Jack, Queen, and King) and an Ace.

A card is chosen at random, its value is recorded, and it is returned to the deck. Then a second card is chosen at random. What is the probability that the first card is an odd number card and the second card is an even number card?

Express your answer as a fraction "A/B" in simplest form.
