Step 7

Express as fractions or percentages the likelihoods of outcomes for situations involving chance, checking for consistency between experimental results and models of all possible outcomes
Find the relative frequency of events
Predict the theoretical probability of an event
Use tree diagrams to explore possible outcomes for a sequence of events
Evaluate statements made by others about the findings of probability activities

Use tree diagram to explore the probability of the game rock, paper, scissors

One card is drawn from a deck of 52 cards:

Two cards are drawn from a deck of 52 cards, one after the other:

Find the probability of selecting a king from the first card.
Find the probability of selecting a 2, 3 or 4 from the first card.
If the first card is king and the card is not replaced, what is the probability of selecting a king from the second card?
If the first card is a jack, queen or king, what is the probability of selecting a jack, queen or king from the second card?

Draw Tree Diagrams to show the possibilities for these situations:

A store sells handbags in two colors: black and white. They are available in 2 different sizes: small and large. What is every possible combination of the color and size of a bag that one can buy?
Sam needs to decide his snack. He can have milk or coffee followed by chocolate chips or peanut butter cookies. What is every possible combination of the drink and food that Sam can have?
Nelly has 2 coins that she tosses one after the other. Draw a tree diagram showing the possible combinations for the two coins.
