Exploring Probability and Statistics

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Probability of an event = (Number of favorable outcomes) / (Total number of possible outcomes).

A sample space is the set of all possible outcomes of a probability experiment.

Independent events do not affect each other's outcomes, while dependent events do.

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points in specified ranges.

The mean is the average of a set of numbers, calculated by dividing the sum of all values by the number of values.

To find the median, arrange the numbers in ascending order and identify the middle value. If there is an even number of values, the median is the average of the two middle values.

The mode is the value that appears most frequently in a data set.

A bar graph is used to compare different categories of data using rectangular bars.

A pie chart is a circular statistical graphic divided into slices to illustrate numerical proportions.
