HIGH SCHOOL:
Probability Basics
Students in 11th and 12th grade Math were presented with the definition of probability
and discussed sample spaces and events. Two major types of probability (theoretical
and empirical) were discussed and explored. Students explored and provided
examples of real-life scenarios to illustrate the different types. Common misconceptions
were investigated such as that probability is always based on luck or chance, emphasizing
that it can also be calculated using mathematical principles. Students then used empirical
probability to make predictions and decisions regarding outcomes.
As a result of instruction, students will be able to:
• calculate probability, both theoretical and empirical and evaluate potential outcomes
of a decision by allotting probabilities to payoff values and computing expected values.
Observations:
Students were using their knowledge of theoretical and empirical probability to make informed
decisions based on the likelihood of events.
MA Standards:
Using Probability to Make Decisions
A. Calculate expected values and use them to solve problems.
B. Use probability to evaluate outcomes of decisions.
