8. Pauline has heard on the news that there will be a comet passing near the Earth.
The weatherman on the news reported that there is a 70% chance that the comet will be
visible if the night sky is clear. If the night sky is not clear, there is only a 15% chance of
being able to see the comet. He has also said that there is a 40% chance that the night sky
will not be clear.
a) If V is the event "the comet is visible" and C is the event "the night sky is clear",
express the following probabilities as reduced fractions.
i) P(C)
ii) P(C')
iii) P(V|C)
iv) P(V|C')
b) Using a tree diagram, determine the odds in favour of Pauline being able
to see the comet.
