Which are the combined events in this game? (the events happening together) Which are the possible outcomes ? We use possibility space diagrams to show the possible outcomes of combined events – try it out! Rock Paper Scissors

Possibility Space Diagrams In a possibility space diagram we list all the possible outcomes of two events happening together and we use them to find the probability of the combined events! EVENT A Possible outcomes of Event A EVENTBEVENTB Possible outcomes of Event B The COMBINED Possible Outcomes

Possibility Space Example Imagine throwing two coins at the same time: A blue one and a red one What are the combined possible outcomes? What is the probability of getting one heads & one tails? HT H{H, H}{H, T} T{T, H}{T, T} Blue Coin Red Coin
