Sketch a venn diagram of these events,
Berkeley and Chelsea visited independently of one another.
Berkeley visited with probability 80%.
iii. Chelsea visited with probability 75%.
However, it often happened that some object in his house - especially if it was fragile - accidentally broke during such visits (not true). Furthermore,
The probability of such an accident occurring, given that both children visited, was 90%.
The probability of such an accident occurring, given that only Berkeley visited, was 35%.
The probability of such an accident occurring, given that only Chelsea visited, was 20%.
vii. The probability of such an accident occurring, given that neither child visited, was 2%.
Sketch and label a Venn diagram for events A = Accident, B = Berkeley visited, and C = Chelsea visited.
