Playing darts involves throwing a dart at a circular board. Within the board are even smaller circles. The best score is given when the middle section is hit. To find out the geometric probability of hitting certain areas of the board such as the bull's-eye, you would need to calculate the total area of the entire board as well as the area of the section that you wish to hit. Then divide the area that you wish to hit by the total area and represent your answer as a percentage. Knowing the formula, pi times radius squared, for finding the area of a circle is imperative for this game.
Shuffle board requires shuffling a puck into a particular area on the game board. The game board is a rectangle. You can determine the chances of hitting a certain section of the board with geometric probability. You will need to calculate the entire area of the board using length times width for a rectangle. You will also need to calculate the area of the section in which you wish for the puck to land. Divide the section area by the total board and give your answer as a percentage.
Geometric probability also plays a part in hitting pins in bowling. For this calculation, you will need to know the width of the lane and the width of the pin. You can divide the width of the pin by the width of the lane and determine the geometric probability in percentage that you will hit the pin.
Skee ball involves throwing a ball into a hole on a board. This geometric probability uses the area of a circle (the hole). You will multiply the area of the hole by the number of holes that there are if you have several options for winning. You will divide the area of the hole(s) by the area of the board to determine the likelihood that the hole is hit.
Dice are cubes and spinners are round. Both have preferred sections for landing. Therefore, geometric probability takes place in games with these tools. Calculate the area of one section on the spinner and multiply it by the number of sections that are winners. Then divide by the total area of the spinners. The same operations can be carried out using faces of the die and the total area of the die.
