Grade 7 - Statistics & Probability

Standard 7.SP.3 - Practice determining the experimental probability of a word problem.

Included Skills:

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.
