A bicycle shop equips 60% of their bikes with a water bottle holder. 55% of the bikes they sell have a kickstand attached to the bike. 34% of the bikes sold have both features.

We can tell that these two features are independent because...
◦ These two features don't have anything to do with each other, so we know they're independent.
◦ The probability of having a kickstand given that you have a water bottle (56.7%) is about equal to the probability of having a kickstand (55%).
◦ The probability of having either feature (81%) doesn't equal the probability of having just one feature (60% and 55%).
◦ The probability of having both features is not zero; it is 34%.
◦ The probability of having both features (34%) does not equal the probability of having neither feature (19%).
