Probabilities from tree

WebbTo draw a probability tree diagram it is necessary to identify all the possible outcomes and the probabilities associated with them. The steps to construct a probability tree are as follows: Step 1: Identify whether the events are dependent or independent. Step 2: Draw branches to represent the first set of outcomes.
