Math Problem Statement

A card is drawn randomly from a standard 52-card deck. Find the probabilities of the given events. The card drawn is a 5.

The card drawn is a face card (Jack, Queen, or King).

The card drawn is not a face card.

Solution

Let's calculate the probabilities of each event step by step:

1. The card drawn is a 5:

In a standard 52-card deck, there are 4 cards that are 5's (one from each suit: hearts, diamonds, clubs, and spades).

P(5)=Number of 5’sTotal number of cards=452=113P(\text{5}) = \frac{\text{Number of 5's}}{\text{Total number of cards}} = \frac{4}{52} = \frac{1}{13}

2. The card drawn is a face card (Jack, Queen, or King):

There are 3 face cards (Jack, Queen, and King) in each of the 4 suits. So, the total number of face cards is:

Number of face cards=3×4=12\text{Number of face cards} = 3 \times 4 = 12

P(Face card)=Number of face cardsTotal number of cards=1252=313P(\text{Face card}) = \frac{\text{Number of face cards}}{\text{Total number of cards}} = \frac{12}{52} = \frac{3}{13}

3. The card drawn is not a face card:

Since there are 12 face cards in the deck, the number of non-face cards is:

Number of non-face cards=5212=40\text{Number of non-face cards} = 52 - 12 = 40

P(Not a face card)=Number of non-face cardsTotal number of cards=4052=1013P(\text{Not a face card}) = \frac{\text{Number of non-face cards}}{\text{Total number of cards}} = \frac{40}{52} = \frac{10}{13}

Final Probabilities:

  • The probability of drawing a 5: 113\frac{1}{13}
  • The probability of drawing a face card: 313\frac{3}{13}
  • The probability of drawing a non-face card: 1013\frac{10}{13}

Here are 5 related questions to expand this:

  1. What is the probability of drawing an Ace from the deck?
  2. What is the probability of drawing a red card?
  3. What is the probability of drawing a heart or a club?
  4. What is the probability of drawing a 10 or a face card?
  5. What is the probability of drawing a card that is either a spade or a number card?

Tip: To improve your probability skills, practice identifying favorable outcomes versus total outcomes for various real-world scenarios.
