  a. Develop a uniform probability model by
     assigning equal probability to all
     outcomes, and use the model to
     determine probabilities of events. For
     example, if a student is selected at
     random from a class, find the probability
     that Jane will be selected and the
     probability that a girl will be selected.
  b. Develop a probability model (which may
     not be uniform) by observing
     frequencies in data generated from a
     chance process. For example, find the
     approximate probability that a spinning
     penny will land heads up or that a
     tossed paper cup will land open-end                                     4.4.7.B.4. Play and analyze probability-    In CCSS, concepts

    event is the fraction of outcomes in the

    events using methods such as organized
    lists, tables and tree diagrams. For an
    event described in everyday language                                          NEW (to grade 7)
    (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?
