Have you seen this question before?

Amazon has a warehouse system where items on the website are located at different distribution centers across a city. Let’s say in one example city, the probability that a specific item X is available at warehouse A or warehouse B are 0.6 and 0.8 respectively.

Given that you’re a customer in this example city and the items are only found on the website if they exist in the distribution centers, what is the probability that the item X would be found on Amazon’s website?
