Probability and Statistics Flashcardizz

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1.

A statistical survey is a method of collecting data from a group to understand characteristics or opinions.

An event is certain if it has a probability of 1, meaning it will definitely happen.

An event is impossible if it has a probability of 0, meaning it cannot happen.

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

A random experiment is a process that leads to one of several possible outcomes, where the outcome cannot be predicted with certainty.

The sample space is the set of all possible outcomes of a random experiment.

The probability is 1/2, since there are two possible outcomes: heads or tails.

A bar graph is a visual representation of data using bars to show the frequency of different categories.

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