Listing Outcomes Objective: To list the outcomes of an event and calculate probability. Lesley Soar Valley College A child’s game has three picture cards. If you choose a card, replace it and choose again, how many different combinations could you get? Here’s a couple to start you off: Write these as: DD DC

Listing Outcomes Objective: To list the outcomes of an event and calculate probability. Lesley Soar Valley College There are 9 different outcomes – can you see how they have been listed? DD DC DM CD CC CM MD MC MM You probably listed yours like this – using letters.

Listing Outcomes Objective: To list the outcomes of an event and calculate probability. Lesley Soar Valley College You could also list them in a sample space diagram DDCDMD DCCCMC DMCMMM You can use the sample space diagram to answer probability questions.

Listing Outcomes Objective: To list the outcomes of an event and calculate probability. Lesley Soar Valley College You can use the sample space diagram to find probabilities. DDCDMD DCCCMC DMCMMM What’s the probability of getting matching cards? 3 9 = 1 3 What’s the probability of getting a dog card? 5 9

Listing Outcomes Objective: To list the outcomes of an event and calculate probability. Lesley Soar Valley College Another game has four different pictures. Draw a sample space diagram to show all the different outcomes of choosing two cards. This is a rabbit! What is the probability of having two matching cards?
