Document Summary
Statistics and probability are closely related elds that deal with the analysis and interpretation of data. Here are some examples of how to solve problems in statistics and probability: probability of an event: the probability of an event happening is the ratio of the number of favorable outcomes to the total number of outcomes. For example, if you roll a fair six-sided die, the probability of rolling a 3 is 1/6, since there is only one favorable outcome (rolling a 3) out of six possible outcomes (rolling a 1, 2, 3, 4, 5, or 6): mean, median, and mode: these are measures of central tendency that describe the average value of a set of data. The mean is the sum of all values divided by the total number of values. The median is the middle value when the data is arranged in order. The mode is the value that occurs most frequently.
