Mrs. Wartenheimer Solves a Problem % & O & File Edit View Tools Help Mrs. Wartenheimer, the 4th grade teacher at Marsburg Elementary decided to assign a research report. She wanted her students to work as partners. The only problem was they all refused to work together. Being a fair and democratic sort of teacher, she wrote their names on slips of paper, put them in a paper bag and shook them up. Cindy began to cry immediately. \"I only want to work with a girl,\" she sobbed. \"There, there, dear, \" soothed Mrs. Wartenheimer. \" You have the same chances as everyone else of having your name drawn with another girl. Tl make you a deal, however. If you can figure out the chances that | will draw two slips of paper out of the bag that both have girl's names on them, I'll let you work with whomever you choose to work with!\" ( Mrs. Wartenheimer had been trying for months to get her students to master probability problems. \"This\" she thought to herself, \"Might be my golden opportunity\".) \"How about me?\" squealed Harvey, \"Can | get the same kind of deal?\". \"I'll tell you what, class\" Mrs. Wartenheimer said reluctantly, \"If you can figure out the answer to three probability questions, I'll let all of you choose your own partners.\" Request edit access Mrs. Wartenheimer's Class: Mrs. Wartenheimer's Class: Mrs. Wartenheimer wrote four questions on the board. \"Alright kids,\" she said. \"Copy these down and figure them out and I'll keep my promise\" 1. What are all of the possible outcomes for the \"pull two names out of a bag\" experiment? 2. What is the probability that | will draw two slips of paper out of the bag that both have girl's names on them? 3. What is the probability that | will draw two slips of paper out of the bag that have one boy's name and one girl's name? 4. What is the probability that | will draw two pieces of paper out of the bag that have two boy's names on them? Hint: Cindy, Irene, and Mary are girls. Bill, Moe, Sam and Harvey are boys. Hint 2: Think about making a tree diagram or an organized chart Activity Reflection What were the most challenging parts of this activity for you? What resources did you use, if any, to complete this activity? What do you feel you understand about probability after this activity? If you started this activity over, what, if anything, would you do differently? What, if anything, would you change about this activity if you were the teacher? Thinking forward to your teaching career, how might you use the concepts learned in this activity in your future classroom
