GCSE Maths Practice: conditional-probability

Question 7 of 10

This question illustrates conditional probability with a subset of cards.

‹ ›

\( \begin{array}{l}\text{A deck of 52 cards contains 13 hearts, 13 diamonds, 13 clubs, and 13 spades.} \\ \text{A card is drawn at random.} \\ \text{What is the probability that it is a heart, given that the card is red?}\end{array} \)

Choose one option:

\( \frac{13}{26} \) \( \frac{1}{4} \) \( \frac{13}{52} \)

Only consider items in the subset defined by the condition.

Restrict the sample space to red cards and count the hearts to calculate probability.
