Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

For example, if you throw a die, then the probability of getting 1 is 1/6. Similarly, the probability of getting all the numbers from 2,3,4,5 and 6, one at a time is 1/6. Hence, the following are some examples of equally likely events when throwing a die: Getting 3 and 5 on throwing a die; Getting an even number and an odd number on a dieDot Plots. Line Graphs. Histograms. Make a Bar, Line, Dot or Pie Graph. Pictographs. Scatter (x,y) Plots. Frequency Distribution and Grouped Frequency Distribution. Stem and Leaf Plots. Cumulative Tables and Graphs.
