1. Introduction 1-1. Probability Simulation Overview • This application performs the six types of simulations described below. Coin Toss Dice Roll Spinner Marble Grab Card Draw Random Numbers (Random Integers) 1-2. Using This Manual • The procedures shown in this manual use the CASIO fx-CG Series calculator.
2. Performing Probability Simulation Operations This section uses Coin Toss to explain how to perform a simulation. Operations for other simulations are identical. 2-1. Using Coin Toss 1. From the Main Menu, enter the Probability Simulation mode. • This displays the simulation selection menu. 2. Press a number button from 1 to 6 to select the simulation you want to use. • Here, press 1(TOSS). • This displays the initial Coin Toss screen. 3. Press 1(TOSS).
• The table below explains the result displayed for each type of simulation.
2-3. Writing Simulation Results into List Memory Example: Coin Toss 1. On the Coin Toss result display, press 3(STORE). • This will display a screen like the one shown below. (The appearance of the screen depends on the simulation type.) 2. For information about what you should do from here, refer to “6. Spreadsheet Mode Memory” in “Chapter 9 Spreadsheet” of the calculator software user’s guide. • For information about List Memory, refer to “Chapter 3 List Function” in the calculator software user’s guide.
3. Configuring Simulation Settings 3-1. Set Up Screen While a result screen is displayed, perform the following operation to display the applicable set up screen: !m(SET UP). Coin Toss Set Up Screen 1(ADV) ....... Display the Advantage set up screen (Coin Toss, Dice Roll, Spinner, and Marble Grab only). 6(INITIAL) ...Returns all items to their initial defaults. Press J to return to the screen you started from. You can use the set up screen to configure settings for the items described below.
Item Description Setting*1 Coin Toss Dice Roll Spinner Marble Grab Card Draw Random Numbers – – – z z – Replacement Specifies whether a drawn marble or card is replaced (On) or not (Off) after being drawn. “ ” is displayed in the upper left corner of the result screen when On is selected for replacement. Repeat Specifies whether the same value can be repeatedly generated (On) or not (Off).
3-2. Advantage Set Up Screen You can use the Advantage set up screen to specify occurrence ratios. Advantage Set Up Screen Examples Coin Toss Marble Grab Use the cursor keys to highlight the item whose setting you want to change. Weight .................... Specify the occurrence ratio weight in a range of 0 to 999. Initial Default: 1 Changing the Weight setting recalculates the Prob value. Prob (Probability) ... Specifies probability as a four-digit decimal value. Examples: 0.5, 0.125, etc.
