GCSE Maths Practice: conditional-probability

Question 9 of 13

This question shows conditional probability in card selection with color restriction.

‹ ›

\( \begin{array}{l}\text{A standard deck of 52 cards has 4 kings.} \\ \text{What is the probability of drawing a king, given that the card drawn is red?}\end{array} \)

Choose one option:

\( \frac{2}{26} \) \( \frac{2}{52} \) \( \frac{1}{26} \)

Always limit the sample space to the subset defined by the condition.

First restrict to red cards, then count kings to calculate the conditional probability.
