Sometimes, one event can affect the outcome of another.

There are 3 red candies left in a bag of multicolored candies with a total of 20 candies left in it. The probability that you will get a red one when you reach in is: 3/20.
But what are your chances of getting a red one if you reach in again?
There are now
19 candies in the bag, and only two are red.
The probability is
Taking the first candy affected the outcome of the next attempt.
The two events are dependent.

  Now you know that the probability of a heads-up landing when you flip a coin is 1/2.

What is the probability of getting tails if you flip it again?
It is still

The two events do not affect each other. They are independent.
