The chance of rain on a given day in Mawsynram is 70%. If it rains, the chance that a food truck will incur a loss on that day is 80%. If it does not rain, then the chance of loss is 10%. On a randomly chosen day if the food truck has not incurred a loss, what is the probability that it had not rained that day? (round to 4 decimal places)
