Exam-Style Question on Sets
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 190. This question is similar to one that appeared on a GCSE Higher paper (specimen) for 2017. The use of a calculator is allowed.
A driving test has two sections, practical(p) and theory(t). One day everyone who took the test passed at least one section. 77% passed the practical section and 81% passed the theory section.
(a) Represent this information on a Venn diagram showing the percentage of candidates in each section of the diagram.
One person is chosen at random from all the people who took the test that day. What is the probability that this person:
(b) passed the practical section, given that they passed the theory section,
(c) passed the theory section, given that they passed only one section?
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription.
Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves.
This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures.
A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience.
