"Two events are independent if the occurrence of one has no effect on the occurrence of the other."  

For example If you have Cheerios for breakfast today and I have Raisin Bran, those two events are independent.  You don't know me and would have no way of knowing what I'm having for breakfast today.

On the other hand, if I have cereal for breakfast, it's going to be with milk.  So my hauling out the cereal is going to influence whether or not I haul out the milk as well, right?

Hope this helps you find the correct answer.
