Common Core (Statistics & Probability)
Common Core for Mathematics
Examples, solutions, videos and lessons to help High School students learn how to weigh
the possible outcomes of a decision by assigning probabilities to
payoff values and finding expected values.
A. Find the expected payoff for a game of chance. For example, find the expected winnings from a state lottery ticket or a game at a fast-food restaurant.
B. Evaluate and compare strategies on the basis of expected values. For example, compare a high-deductible versus a low-deductible automobile insurance policy using various, but reasonable, chances of having a minor or a major accident.
