GCSE Maths Practice: conditional-probability

Question 1 of 10

This question practices conditional probability with two draws without replacement.

›

\( \begin{array}{l}\text{A bag contains 10 red, 8 green, and 4 blue balls.} \\ \text{Two balls are drawn without replacement.} \\ \text{What is the probability that the second ball is red, given that the first ball was green?}\end{array} \)

Choose one option:

Always adjust the total number of balls and count remaining items when computing conditional probability.

Remove the first ball from the total before computing probability for the second ball. The count of remaining items matters.
