Easy -1.8 This is a 1-mark multiple choice question requiring only the basic principle that probabilities in a Venn diagram sum to 1. Students simply add the given probabilities and subtract from 1 to find x. It's a routine recall question with no problem-solving required, significantly easier than average A-level questions.
The probabilities of events \(A\), \(B\) and \(C\) are related, as shown in the Venn diagram below.
