  • Probability of drawing a face card:
  • Probability of not drawing a face card:
  • Odds in favor of drawing a face card:
  • Odds against drawing a face card:

Solución

Step 1: Find the probability of drawing a face card.
A face card is a Jack, Queen, or King. There are 3 face cards per suit and 4 suits, so there are
in a standard 52-card deck. Thus, the probability is
Step 2: Find the probability of drawing a card that is not a face card.
There are
Thus, the probability is
Step 3: Determine the odds in favor of drawing a face card.
Odds in favor are given by the ratio of the number of successful outcomes (face cards) to the number of unsuccessful outcomes (non-face cards):
Simplify the ratio by dividing both numbers by 4:
Step 4: Determine the odds against drawing a face card.
Odds against are the inverse ratio (non-face cards to face cards):
Simplify the ratio by dividing both numbers by 4:
Final Answers:
  • Probability the card drawn is a face card:
  • Probability the card drawn is not a face card:
  • Odds in favor of drawing a face card:
  • Odds against drawing a face card:

Bonus Knowledge

In a standard 52-card deck, there are 12 face cards (Jack, Queen, King across four suits). The probability of drawing a face card is therefore 12 out of 52, which simplifies to . Conversely, drawing a card that is not a face card occurs 40 times, leading to the probability of or .
To find the odds in favor of drawing a face card, you compare the number of successful outcomes (face cards) to the number of unsuccessful outcomes (non-face cards). Thus, the odds in favor are 12 to 40, simplifying to 3 to 10. On the other hand, the odds against drawing a face card would be 40 to 12, or simply 10 to 3. Make sure to double-check your calculations—it’s easy to miss a simplification!
