WebbStep 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. Step 3: Multiply along the branches and add vertically to find the probability of the outcome. Example: WebbThe last two draws follow logically: 2 acceptable numbers out of 58, and then 1 acceptable number out of 57. So the probability of drawing any particular set of 4 numbers out of 60, if we cannot draw any number twice, is: (4/60) * (3/59) * (2/58) * (1/57)
