Summary: Whether students are beginning their study of probability or are well into it, distinctions between complementary sets and mutually exclusive sets can be confusing. Cathy Schloemer writes in this article that for years she used typical classroom examples but was not happy with the student engagement or the level of understanding they produced. Here she provides one experience she had with alternative examples that helped make this one of her favorite lessons. (ERIC)
