The correct Answer is:
To solve the problem, we need to determine the probability of drawing a heart and the probability of drawing a king from a modified deck of playing cards. ### Step-by-Step Solution: 1. **Determine the Total Number of Cards Remaining**: - A standard deck has 52 cards. - The King, Queen, and Jack of clubs are removed. - Therefore, the total number of cards remaining is: \[ 52 - 3 = 49 \] 2. **Calculate the Probability of Drawing a Heart**: - In a standard deck, there are 13 hearts. - Since we have not removed any hearts, the number of hearts remains 13. - The probability \( P(\text{Heart}) \) is given by the formula: \[ P(\text{Heart}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{13}{49} \] 3. **Calculate the Probability of Drawing a King**: - In a standard deck, there are 4 kings (one for each suit). - We have removed the King of clubs, so the number of kings remaining is: \[ 4 - 1 = 3 \] - The probability \( P(\text{King}) \) is given by: \[ P(\text{King}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{3}{49} \] ### Final Answers: - The probability of drawing a heart is \( \frac{13}{49} \). - The probability of drawing a king is \( \frac{3}{49} \).
