Objectives
7.SP.8
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?
I Can…
• Extend the principles of probability of simple events
to compound events
• Represent sample spaces for compound events
using multiple methods such as organized lists,
tables and tree diagrams
• Find the probability of compound events based on
the sample space
• Design and use a simulation to generate
frequencies for compound events
• Find the probability of compound events based on
the simulation
