Lesson 14

Part III (Introduction to NumSolve and Probability, continued)

In this part, you will learn how to use the Probability application. Probability is another very simple application that can be used to roll dice in multiple ways and generate data quickly.

1. Finding Probability

2. Exploring Probability

3. Viewing the Data Generated by Rolling Dice Graphically

4. Step 3 Continued...

Part III


Practice Exercises

  1. Please begin by opening the Main application and clearing the window. Thank you!
  2. Open the Probability application.
  3. Turn the radio button on for 2 Dice *.
  4. Set the Number of trials to 10 and Number of faces to 3.
  5. Click OK.
  6. Without clearing the window, roll the dice again using type 2 Dice * and 3 faces again but change Number of trials to 100.
  7. Resize the Probability window so that both rolls show.
  8. With both rolls showing, get a screen capture. Paste it into your Lesson14 document (under a title of PART III).
  9. Resize the window again so that the Main window shows.
  10. In Main, type in trn( and then drag the matrix from the second roll up (with 100 trials).
  11. Press EXE.
  12. From within Main, open the List Editor.
  13. Select your turned matrix and drag it into the List Editor.
  14. With Main and the List Editor windows showing, get a screen capture. Add two blank spaces following the first screen capture and then paste this one.
  15. Draw a histogram for your data using an HStep of 1.
  16. With the histogram showing, get a screen capture. Add two blank spaces following the last screen capture and then paste this one.

Part IV

Written Exercises

Please copy and paste the following questions into your Lesson14 document (under a title of Part IV) and answer them.

  1. What application uses flash memory?
  2. Name two applications, other than Main, that can use a variable defined in the Main application. There are many possible answers.
  3. What happens when we define a variable in Main and then use the same variable name in NumSolve?
  4. How many unknowns can NumSolve solve for at one time?

Reflection Exercises

You have just completed the fourteenth lesson in ClassPad 101. In the next lesson we will begin programming and will use MCS memory again. Please take a few moments to copy and paste the following four questions at the end of your Lesson14 document and answer them.

  1. Approximately how long did it take you to complete this lesson?
  2. Which activity did you find particularly useful?
  3. Did you find any part of this activity difficult to follow? If so, which part? Also, how did you overcome the difficulty?
