A dashboard warning light should flash red when a car's oil level is too low. Suppose on a certain model of cars, given the oil level is low, the probability of the light flashing is 99%. Suppose also that 2% of the time, this light flashes for no reason. If in fact there is a 10% chance the oil level is actually low in this car, while a 90% chance the oil level is OK. What is the probability that the oil level is actually low when the light flashes?
