What is the probability of drawing a pencil from the bag containing 6 items?

**OVERALL EXPECTATION**

D1. manage, analyse, and use data to make convincing arguments and informed decisions, in various contexts drawn from real life.

D1.1 explain why

**percentages**are used to represent the distribution of a variable for a population or sample in large sets of data, and provide examplesD1.2 collect qualitative

**data****and discrete and continuous quantitative data to answer questions of interest, and organize the sets of data as appropriate, including using percentages**D1.3 select from among a variety of graphs, including

**circle graphs**, the type of graph best suited to represent various sets of data; display the data in the graphs with proper sources, titles, and labels, and appropriate scales; and justify their choice of graphsD1.4 create an infographic about a data set, representing the data in appropriate ways, including in tables and

**circle graphs**, and incorporating any other relevant information that helps to tell a story about the dataD1.5 determine the impact of adding or removing data from a data set on a measure of central tendency, and describe how these changes alter

**the shape and distribution of the data**D1.6 analyse different sets of data presented in various ways, including in

**circle graphs**and in misleading graphs, by asking and answering questions about the data, challenging preconceived notions, and drawing conclusions, then make convincing arguments and informed decisionsD1.1 identify situations involving

**one-variable data**and situations involving**two variable data**, and explain when each type of data is neededD1.2 collect

**continuous data**to answer questions of interest involving two variables, and organize the data sets as appropriate in a table of values D1.3 select from among a variety of graphs, including

**scatter plots**, the type of graph best suited to represent various sets of data; display the data in the graphs with proper sources, titles, and labels, and appropriate scales; and justify their choice of graphsD1.4 create an infographic about a data set, representing the data in appropriate ways, including in tables and

**scatter plots**, and incorporating any other relevant information that helps to tell a story about the dataD1.5 use mathematical language, including the terms

**“strong”, “weak”, “none”, “positive”, and “negative”**, to describe the relationship between two variables for various data sets with and without outliersD1.6 analyse different sets of data presented in various ways, including in

**scatter plots**and in misleading graphs, by asking and answering questions about the data, challenging preconceived notions, and drawing conclusions, then make convincing arguments and informed decisions**OVERALL EXPECTATION**

**D2. describe the likelihood that events will happen, and use that information to make predictions**

D2.1 describe the difference between independent and dependent events, and explain how their probabilities differ, providing examples

D2.2 determine and compare the theoretical and experimental probabilities of two independent events happening and of two dependent events happening

D2.1 solve various problems that involve probability, using appropriate tools and strategies, including Venn and tree diagrams

D2.2 determine and compare the theoretical and experimental probabilities of multiple independent events happening and of multiple dependent events happening
