WHAT DO YOU EXPECT? 1.2 Finding More Probabilities Learning Target: I will conduct an experiment and write probabilities of possible outcomes as fractions. HW: Complete the WDYE Investigation 1 Pg.5 and Correct with the Zaption video: WDYE 1.2 Warm Up: 1) Is it possible to toss a coin 20 times and have it land heads up 20 times? 2) Is this likely? Explain.

Conduct your own experiment: 4. Which of the cup’s landing positions should Kalvin use to represent Cocoa Blast? _____________ Explain:  

Class Data: For what fraction of our class tosses did the cup land on one of its ends? ________ What percent is this? ________ 5. Based on our class data, would you change your answers to the precious questions? 3. Do the landing positions end and side have the same chance of occurring? ________ If not, which is more likely? ____ Explain: 4. Which of the cup’s landing positions should Kalvin use to represent Cocoa Blast? ______ Explain: Ends

D. Kalvin’s mother agrees to let him use a cup to decide his cereal each morning. On the first morning, the cup lands on its end. On the second morning, it lands on its side. Kalvin says, “This cup isn’t any better than the coin. It lands on an end 50% of the time!” Do you agree or disagree with Kalvin? Explain. Two trials are not enough to give a good estimate of chances … Kalvin needs to toss the paper cup many times to make a good estimate.
