We know that the essence of probability is writing a ratio between the number of successful outcomes to the total number of possible outcomes. This is true when applied to geometric probability, as well. Geometric probability is based on area and deciding what proportion of the total area is in each different grouping. Here we look at a classic "spinner" example where we try to determine the probability that a spinner will land on a certain color. We also look at a more complicated shaded area situation where we will write the ratio of shaded area to the total rectangle area.
