Grade 7 - Statistics & Probability
Standard 7.SP.3 - Calculate the total number of possible outcomes of compound events.
Included Skills: Stats
Demonstrate an understanding of theoretical and experimental probabilities for two independent events where the combined sample space has 36 or fewer elements. • Explain what a probability tells about the situation to which it refers. • Provide an example of two independent events, such as: - spinning a four section spinner and an eight-sided die - tossing a coin and rolling a twelve-sided die - tossing two coins - rolling two dice and explain why they are independent. • Identify the sample space (all possible outcomes) for each of two independent events using a tree diagram, table, or another graphic organizer. • Determine the theoretical probability of an outcome involving two independent events. • Conduct a probability experiment for an outcome involving two independent events, with and without technology, to compare the experimental probability to the theoretical probability. • Solve a probability problem involving two independent events. • Explain how theoretical and experimental probabilities are related and why they cannot be assumed to be equal. • Represent a probability stated as a percent as a fraction or a decimal. • Represent a probability stated as a fraction or decimal as a percent.
