Answer:
The answer is "64".
Step-by-step explanation:
Let A= look at the number of a card on it {3,5,7,9}
[tex]\to 4 \times 4 = 16 \ odd \ numbers[/tex]
Let B= look at the king of the card = [tex]4 \ Cards[/tex]
Choose one card A = 16 ways
Choose one card B= 4 ways
selecting one card, either A and B:
