How to Generate Frequencies for Compound Events? Generating frequencies is an important aspect in the field of statistics. The concept of chances is essential to learn the probabilities of compound events. There are many methods to calculate frequencies for compound events. Simulation is probably the easiest and most effective method, followed by random number tables. You need to select a simulation method beforehand. Let us consider an example. If a baseball player makes five out of eight foul shots, then we can use a colored disk to simulate a foul shot. For instance, a blue-colored disk depicts a completed shot and a red disk could identify as a miss. Now, put five blue disks, three red disks and any other color in a container. Now mix them, and randomly select a disk to represent a foul shot. If the color of the disk you take out of the container is blue, then the batter hit the shot; if it's red, then he misses. If a different color comes out of the container, then it’s a foul shot. A series of worksheets and lessons that teach students to use a variety of different methods to determine the probability of compound events.
