GCSE Maths Practice: conditional-probability

Question 10 of 13

This question illustrates conditional probability with face cards as the subset.

‹ ›

\( \begin{array}{l}\text{A standard deck of 52 cards is used.} \\ \text{A card is drawn and it is known to be a face card.} \\ \text{What is the probability that it is a king?}\end{array} \)

Choose one option:

\( \frac{1}{3} \) \( \frac{4}{13} \) \( \frac{1}{13} \)

Count only items in the subset defined by the condition to compute probability.

Restrict sample space to face cards, then count kings to compute probability.
