In these lessons, we will learn how to calculate probability without replacement dependent events and how to use a probability tree diagram. In some experiments, the sample space may change for the different events. For example, a marble may be taken from a bag with 20 marbles and then a second marble is taken without replacing the first marble. The sample space for the second event is then 19 marbles instead of 20 marbles. This is called probability without replacement or dependent probability. We can use a tree diagram to help us find the probability without replacement. Step 1: Draw the Probability Tree Diagram and write the probability of each branch. Remember that the objects are not replaced Step 2: Look for all the available paths or branches of a particular outcome.
