Explanation: If events are dependent, this means that the outcome of the first event will affect the outcome of the second event.
Let's look at an example.
Gianna has 8 blue socks and 4 red socks in her sock drawer. She chooses one sock at random and puts its on. She then chooses another sock without looking. Find the probability of the following event.
P (red, then red)
These would be dependent events because if she puts a sock on and doesn't replace it, there is 1 fewer sock in the drawer which affects the probability.
