The operation process of generating random numbers in Geometric Sketchpad

Step 1 Draw a line segment AB, pick any point C on it, measure the ratio of the three points A, B, and C, and change the label to t. The value range of t is the closed interval of [0,1].

Step 2 Select point C and execute [Edit] - [Operation Button] - [Animation] to generate an animated button named SJ.

Step 3 Click button SJ, point c starts to move, and the value of t is constantly changing. We select line segment AB and point C and press [Ctrl H] to hide them.

Step 4 Select button SJ and right-click to open the property setting dialog box. Set the animation mode to [Random] in the direction bar and click OK.

Step 5 Click button SJ, the value of t is a random number between 0 and 1. With random numbers between 0 and 1, you can generate random numbers in any range, and you can further generate random integers.
