GCSE Maths Practice: conditional-probability

\( \begin{array}{l}\text{A bag contains 10 balls: 4 red, 3 green, and 3 blue.} \\ \text{One ball is drawn at random and not replaced.} \\ \text{What is the probability the second ball is blue, given the first was green?}\end{array} \)

Choose one option:

\( \frac{3}{9} \) \( \frac{3}{10} \) \( \frac{2}{9} \)
