The student divided the number of wins by the number of losses. The student should have divided the number of wins by the total number of games. The student should have first added 20 and 10 to find that there were a total of 30 games.

Final answer:

The question spans various statistical concepts in mathematics such as creating stem-and-leaf plots, calculating probabilities, constructing histograms, and working with ratios and percentages.

Step-by-step explanation:

The question involves using statistical methods to analyze data related to sports teams, games, and probabilities. For example, when we want to create a side-by-side stem-and-leaf plot, we are organizing data to visually compare distributions. Similarly, calculating the probability of winning a game multiple times requires understanding and applying binomial probabilities.

To answer the different scenarios provided, one must be comfortable with concepts such as probability theory, data representation with plots and histograms, and basics of statistical analysis like ratios and percentages. The example where we calculate fractions and cross-multiply to find a percent illustrates fundamental ratio and proportion problem-solving methods taught in many mathematics courses.
