An urn contains three electronically labeled balls with labels 00, 01, 10. Lisa, Homer, and Bart are asked to characterize the random experiment that involves selecting a ball at random and reading the label. Lisa's label reader works fine; Homer's label reader has the most significant digit stuck at 1; Bart's label reader's least significant digit is stuck at 0. (a) What is the sample space determined by Lisa, Homer, and Bart? (b) What are the relative frequencies observed by Lisa, Homer, and Bart in a large number of repetitions of the experiment?
