7-SP8

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. [7-SP8a]

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. [7-SP8b]

c. Design and use a simulation to generate frequencies for compound events. [7-SP8c]
  • 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?

My Humble Opinion
This objective was in ACOS 2003/2009 for 7th grade except for simulations. This was in 8th grade. Designing a simulation is completely new.
