GCSE Maths Practice: conditional-probability

Question 6 of 10

This question shows conditional probability for multiple outcomes when a color is excluded.

\( \begin{array}{l}\text{A box contains 8 white, 6 red, and 4 blue balls.} \\ \text{A ball is drawn at random and replaced.} \\ \text{What is the probability the ball is white or red, given that it is not blue?}\end{array} \)

Choose one option:

Count remaining items that satisfy the condition before computing probability.

Focus on remaining items (white or red) after excluding the given condition (blue).
