CCSS Description: Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation. a. Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs. b. Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language (e.g., “rolling double sixes”), identify the outcomes in the sample space which compose the event. c. Design and use a simulation to generate frequencies for compound events. For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood?
This worksheet is designed to lead learners through a process of using their knowledge of equivalent fractions and ratios to solve problems involving the capture recapture sampling method. Section A provides some recap quections of finding the missing value in equivalent fractions and ratios. Section B then provides some tables to complete so that the proportions of marked items in a sample are the same as the marked items in a population. Section C then has some exam styles word problems involving capture recapture sampling.
