Probability (Dependent & Independent Events)




 

Videos and lessons to help Grade 7 students learn how to find probabilities of compound events using organized lists, tables, tree diagrams, and simulation.

A. Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.

B. Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”), identify the outcomes in the sample space which compose the event.

C. Design and use a simulation to generate frequencies for compound events. For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood?

Common Core: 7.SP.8

Suggested Learning Targets

  • I can use tree diagrams, frequency tables, and organized lists to determine the probability of a compound event.
  • I can identify the outcomes in a sample space.
  • I can represent probability outcomes as fractions, decimals, or percents.
  • I can design a simulation to estimate the probability of a compound event.
