Question

Angelica has a deck of 52 cards with 4 suits (hearts, spades, diamonds, and clubs), and each suit has cards numbered 1–13. Calculate the complement of not picking a 6. The answer should be a fraction. Remember to simplify.(1 point)

To find the complement of not picking a 6 from a standard deck of 52 cards, we first need to determine the total number of favorable outcomes and then calculate the complement.

  1. Total number of cards in the deck: There are 52 cards in total.

  2. Number of favorable outcomes for not picking a 6: There are 4 sixes in the deck (one from each suit: hearts, spades, diamonds, clubs). So, the number of cards that are not a 6 is: \[ 52 - 4 = 48 \]

  3. Probability of not picking a 6: The probability of not picking a 6 is given by the number of non-6 cards divided by the total number of cards: \[ P(\text{not picking a 6}) = \frac{48}{52} \]

  4. Complement of not picking a 6 (which is picking a 6): The complement probability can be found by subtracting the probability of not picking a 6 from 1: \[ P(\text{picking a 6}) = 1 - P(\text{not picking a 6}) = 1 - \frac{48}{52} \] \[ = \frac{52}{52} - \frac{48}{52} = \frac{4}{52} \]

  5. Simplifying the fraction: The fraction \(\frac{4}{52}\) can be simplified by dividing both the numerator and the denominator by their GCD, which is 4: \[ \frac{4 \div 4}{52 \div 4} = \frac{1}{13} \]

Thus, the complement of not picking a 6 is \(\frac{1}{13}\).
