GCSE Maths Practice: conditional-probability

Question 3 of 13

This question practices conditional probability with elimination. Remove the excluded items first.

‹ ›

\( \begin{array}{l}\text{A bag contains 5 red balls, 3 green balls, and 2 blue balls.} \\ \text{One ball is drawn at random.} \\ \text{What is the probability the ball is green, given that it is not red?}\end{array} \)

Choose one option:

\( \frac{3}{5} \) \( \frac{3}{10} \) \( \frac{3}{8} \)

Identify which items are excluded, then compute probability from remaining items.

Conditional probability limits the sample space to the given condition. Count only the remaining items for calculation.
