Probability Concepts

Favorable outcomes

• the number of times the desired outcome occurs.

• the total number of possible outcomes.

• the likelihood of an event occurring.

• the average result of multiple trials.

Complement

• probability

• complement

• event

• outcome

Compound event

A _______ event is made up of two or more single events, each with different possible outcomes.

• Simple

• Compound

• Independent

• Dependent

Theoretical probability

• probability based on favorable outcomes divided by total possible outcomes.

• probability based on experimental results and observations.

• probability that is always equal to 1.

• probability that cannot be calculated.

fractions, decimals, or percents

• whole numbers, integers, or fractions

• fractions, decimals, or percents

• ratios, averages, or means

• decimals, integers, or whole numbers

Trial

• each representation or observation of an experiment.

• a method of collecting data.

• a hypothesis that is tested.

• the final result of an experiment.

Experiment

• an activity involving chance that can have different results.

• a systematic investigation to establish facts.

• a method of collecting data through observation.

• a process of testing a hypothesis under controlled conditions.

Probability scale

• A diagram showing the probability scale from impossible (0%) to certain (100%).

• A chart representing different types of probability distributions.

• A graph illustrating the relationship between probability and outcomes.

• A table listing various probability formulas.

Outcomes

• possible results of an experiment.

• the methods used in an experiment.

• the materials required for an experiment.

• the hypothesis being tested.

Probability

• Probability is the likelihood that an event will occur, expressed between 0 and 1 or 0% to 100%.

• Probability is the certainty that an event will occur, expressed as a whole number.

• Probability is the chance of an event not occurring, expressed as a negative value.

• Probability is the measure of how often an event has occurred in the past.
