The Venn diagram below shows three events AAA, B B\,B and CCC.

A rectangular sample space contains circles A, B and C, with A overlapping B, B overlapping C, and regions labelled 0.15, 0.25, 0.1, p, q and r.

Events A A\,A and B B\,B are independent.

The probability of C C\,C is 0.4

Write down two of the events that are mutually exclusive and find the values of ppp, q q\,q and rrr.
