You can put this solution on YOUR website! Dependent events are such that when one occurs, it affects the other.
The weather for consecutive days is dependent. If the first day is hot and dry with known high pressure overhead, the second day has a high probability of same.
Rolling dice is independent. What comes up on one is not influenced by the other.
Taking one card from a deck of 52 changes the probability of what will be drawn slightly, because the second event is based on 51 cards, not 52. The first event has changed the second.
Polls based on questions asked on the Internet are biased. The result of one person is correlated with the result of another, because both of these people answered the poll and were not chosen randomly.
