Question 76

The Venn diagram shows the probabilities associated with three events, AAA, B B\,B and CCC. A rectangle contains overlapping circles A and B, a smaller circle C inside B, and the probabilities 0.18, 0.12, 0.04, 0.24, and 0.42 in the indicated regions.

a.

Write down the two events that are mutually exclusive.

b.

Given that p=0.24p=0.24p=0.24 and q=0.42q=0.42q=0.42, verify that A A\,A and B B\,B are independent.
