SF7 Chapter 9 Vocabulary

The sum of probabilities is 1 or 100%.

• Random

• Theoretical probability

• Complementary events

• Inequality

An event consisting of two or more simple events

• Simple event

• Experimental probability

• Sample space

• Compound events

Two or more events in which the outcome of one event affects the outcome of the other events

• Statistics

• Dependent events

• Simple event

• Outcome

An estimated probability based on the relative frequency of positive outcomes ocurring during an experiment. It is based on what ACTUALLY happens.

• Simple event

• Random

• Experimental probability

• Theroetical probability

Two or more events where the outcome of one event does NOT affect the outcome of the other events.

• Independent events

• Dependent events

• Sample space

• Theoretical probability

The chance that some event will happen. This is the ratio of the number of favorable outcomes to the number of possible outcomes.

• Random

• Sample space

• Compound events

• Probability

When outcomes occur by chance, they are said to be this....

• Population

• Survey

• Random

• Convenience sample

This the set of all possible outcomes of a probability experiment

• Sample space

• Dependent events

• Complementary events

• Simple event

An event that has one outcome or a collection of outcomes is called a

• Biased sample

• Experimental probability

• Simple event

• Dependent events

The ratio of the number of ways an event can occur to the number of possible outcomes. This is based on what SHOULD happen when conducting a probability experiment.

• Simple event

• Experimental probability

• Compound events

• Theoretical probability
