Dice Simulator Create an application that simulates rolling a pair of dice. When the user clicks a button, the application should generate two random numbers, each in the range of 1 through 6, to represent the value of the dice. Use PictureBox controls to display the dice. (In the Student Sample Programs, in the Chap05 folder, you will find six images named Die1.bmp, Die2.bmp, Die3.bmp, Die4.bmp, Die5.bmp, and Die6.bmp that you can use in the PictureBoxes.)

9. Tree Age (Python) Counting the growth rings of a tree is a good way to tell the age of a tree. Each growth ring counts as one year. Use a Canvas widget to draw how the growth rings of a 5-year-old tree might look. Then, using the create_text method, number each growth ring starting from the center and working outward with the age in years associated with that ring.

ne: ID: A 7. A game is played by moving a game piece left or right along a horizontal game board. The board consists of spaces of various colors, as shown. The circle represents the initial location of the game piece. Yellow Black Green Green Red Yellow Yellow Black Black Black The following algorithm indicates how the game is played. The game continues until the game is either won by landing on the red space or lost when the piece moves off either end of the board. Step 1: Place a game piece on a space that is not red and set a counter to 0. Step 2: If the game piece is on a yellow space, move the game piece 3 positions to the left and go to step 3. Otherwise, if the game piece is on a black space, move the game piece 1 position to the left and go to step 3. Otherwise, if the game piece is on a green space, move the game piece 2 positions to the right and go to step 3. Step 3: Increase the value of the counter by 1. Step 4: If game piece is on the red space or moved off the end of the…
