An example of dependent events is drawing a green marble out of one jar and then drawing
a)red marble out of another jar
b)green marble out of another jar
c)red marble out of the same jar, without replacing the first marble
d)green marble out of the same jar, after replacing the first marble

Dependent events involve a first event that affects the outcome of a second event. This means that the probability for the second event has changed because of the occurrence of the first event. This is usually present in probabilities without replacement because each event has a different condition. The answer is C)red marble out of the same jar,without replacing the first marble.
