Dependent events
Two events are dependentif the outcome of the first
event affects the outcome of the second event, so that probabilities are
changed.
Example
Let, we have 3 black and 6 green balls in a bag. We pull out one ball,
which may be black or green. Now there are 8 balls left in the bag. Now if we draw another
ball from the bag, now the color of ball drawn, will be effected by the color
of balls drawn in first event, so these two events are dependent.
Independent events
Two events are called independent, if the probability of one
event is independent of occurrence or non-occurrence of other events.
Example
if we put a coin in the air and get the result as
Head, we will again if we put the coin but this time we get the result as Tail.
In both cases, there is a difference between the two. Its means that in both of
the events the outcomes are independents.
