# Conditional Probability # Conditional Probability

The start of the lesson is used to review calculating the probability of two independent events using a tree diagram.  To extend on this in the development phase students begin to consider conditional probability where the outcome of the second event is dependent on the first.   The plenary consolidates the learning through a traditional exam style question.
##### Differentiated Learning Objectives
• All students should be able to draw a tree diagram for conditional events.
• Most students should be able to calculate the probability for two conditional events using a tree diagram.
• Some students should be able to calculate the probability for two or more conditional events using a tree diagram.
