## Exam Style Question## Worked solutions to typical exam type questions that you can reveal gradually |

Question id: 71. This question is similar to one that appeared in an IB Standard paper in 2014. The use of a calculator is not allowed.

Let \(J\) and \(T\) be independent events, where \(P(J)=0.4\) and \(P(T)=0.7\).

(a) Find \(P(J\cap T)\).

(b) Find \(P(J\cup T)\).

(c) Draw a two-set Venn diagram and shade the region that represents \(J\cap T'\).

(d) Find \(P(J\cap T')\).

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. |
