HS.S-MD

HS.S-MD.1(+)Define a random variable for a quantity of interest by assigning a numerical value to each event in a sample space. Graph the corresponding probability distribution using the same graphical displays as for data distributions.HS.S-MD.2(+)Calculate the expected value of a random variable; interpret it as the mean of the probability distribution.HS.S-MD.3(+)Develop a probability distribution for a random variable defined for a sample space in which theoretical probabilities can be calculated; find the expected value.HS.S-MD.4(+)Develop a probability distribution for a random variable defined for a sample space in which probabilities are assigned empirically; find the expected value.HS.S-MD.5(+)Weigh the possible outcomes of a decision by assigning probabilities to payoff values and finding expected values.HS.S-MD.6(+)Use probabilities to make fair decisions (e.g., drawing by lots, using a random number generator).HS.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).
