1. Assume that there is a 50% chance of hard drive damage if a power line to which a computer is connected is hit during an electrical storm. There is a 5% chance that an electrical storm will occur on any given summer day in a given area. If there is a 0.1% chance that the line will be hit during a storm, what is the probability that the line will be hit and there will be hard drive damage during the next electrical storm in this area? 2. Bayes Theorem? P(A|B) = (P(B|A) * P(A))/ P(B) 3. I'm thinking it has something to do with Bayes Theorem... P(hard drive damage) = 0.5 P(electrical storm) = 0.05 P(line hit) = 0.001 I started off by figuring out what is the probability of the line getting hit: P(l|es) = (0.001 * 0.05)/ 0.05 = 0.001 but I'm not sure what I should do next and if my P(l|es) is correct.
