The Union and Intersection of Two Sets - Statistics LibreTexts

WebbThe probability of both events happening is \(0.003\). What is the probability that at least one of the events will happen on a particular day? Solution: Let \(R\) be the event of the windshield getting hit with a rock. Let \(F\) be the probability of getting a flat tire.
