A bag has 4 green balls and 6 yellow balls. What is the probability of drawing a green ball?

Answer and explanation

Correct answer: \(\frac{2}{5}\)

There are \(4+6=10\) balls in total, and the favourable outcomes, i.e. green balls, are \(4\). Hence, the probability is \(\frac{4}{10}=\frac{2}{5}\). \(\frac{3}{5}\) is the probability of drawing a yellow ball, not a green ball. Exam tip: Divide favourable outcomes by total outcomes.
