GCSE Maths Practice: conditional-probability

Question 7 of 13

This question shows conditional probability where only females remain if not male.

\( \begin{array}{l}\text{A group of 50 students contains 20 males and 30 females.} \\ \text{If a student is selected at random, what is the probability the student is female,} \\ \text{given that they are not male?}\end{array} \)

Choose one option:

If only one type remains under the condition, probability is 1.

Focus on students who satisfy the condition (not male) and calculate probability.
