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 questions for 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 worded capture-recapture exam-style questions.
