The Venn diagram below shows three events $A$ , $B\,$ and $C$ .

Venn diagram for Question 2 showing three sets A, B, and C. Sets A and B overlap on the left, while set C is separate on the right. The regions are labeled as follows: A only: 0.2; B only: q; C only: r; A and B only: p; The region outside all three sets is labeled 0.1.

Write down two of the events that are mutually exclusive.

[1]

The probability of $A\,$ is 0.4

The probability of $A\,$ or $B\,$ is 0.7

Find the values of $p$ , $q\,$ and $r$ .
