Use probability to evaluate outcomes of decisions
Grade 912
S.MD.5.
(+) Weigh the possible outcomes of a decision by assigning probabilities to payoff values and finding expected values.
S.MD.5.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 fastfood restaurant.
S.MD.5.b.
Evaluate and compare strategies on the basis of expected values. For example, compare a highdeductible versus a lowdeductible automobile insurance policy using various, but reasonable, chances of having a minor or a major accident.
S.MD.6.
(+) Use probabilities to make fair decisions (e.g., drawing by lots, using a random number generator).
S.MD.7.
(+) Analyze decisions and strategies using probability concepts (e.g., product testing, medical testing, pulling a hockey goalie at the end of a game).
