A meteorologist reports that there is a 30% chance the temperature will fall below freezing tomorrow. On any given day, the bus
has a 60% chance of being late. Assuming the bus travels independently of temperature, what is the probability that a passenger would be waiting for a late bus in freezing weather?
So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.
