Probability
These lessons are designed to reinforce the
following State Math Standards Explore sample
spaces to predict likely outcomes, as well as the
manner in which these predictions affect the
decision making process.(MO 1.3, 1.7, 1.10,
3.6) Develop and execute experiments or
simulations to predict and determine probable
outcomes. (MO 1.2, 1.3, 3.1, 3.6)
