Step by Step Explanation:
  1. According to the question, Ruth randomly withdrew a card from the deck of cards.
    Total number of cards in the deck = 52
    Composite numbered cards in the deck = {(4, 6, 8, 9, 10) = Clubs,
    (4, 6, 8, 9, 10) = Diamonds,
    (4, 6, 8, 9, 10) = Hearts,
    (4, 6, 8, 9, 10) = Spades}
    Total composite cards = 20
  2. Probability that the number on the card is a composite number =  
    Total composite cards in the deck
    Total number of cards in the deck
     
    =  
    20
    52
     
  3. Hence, the probability that the number on the card is a composite number =  
    20
    52
          .
