STAT Module 2 Part I.

A random phenomenon is

• A planned event with a predictable outcome.
• A scientific experiment with controlled variables.
• An event that can have multiple outcomes without knowing which outcome will happen.

• A common occurrence that happens regularly.

In statistics, a trial is

• Each occasion upon which we observe a random phenomenon

• A collection of data points
• A set of observations
• A group of experiments

In statistics, an outcome is

• The process of making a decision.
• The middle point of a process.
• The result of an experiment or each trial.

• The starting point of a process.

An event is

• Combined outcomes

• Common result
• Random occurrence
• General outcome

The collection of all possible outcomes is

• the sample space

• the outcome set

• the event space

• the result range

_______ is the measure of how likely it is for an event to occur.

• Probability
• Certainty

• Likelihood
• Chance

When we see P(A), we're looking for the

• percentage of event A happening

• probability of trial A happening

• percentage of event A happening

• probability of event A happening

What is an example of an event that has equally likely outcomes in an event

• Flipping a biased coin
• Drawing a card from a deck with missing cards
• Rolling a six-sided die

• Choosing a number between 1 and 10

Type Yes or No.

Are all events equally likely?

When finding the probability of an event, this is our

• denominator

• numerator
