Vocabulary review Probability

a model where each outcome does NOT have the same probability of occurring

• fundamental counting principal

• sample space

• non uniform model

• probability

Answer explanation

A non-uniform model is one where different outcomes have different probabilities of occurring, unlike a uniform model where all outcomes are equally likely. This makes 'non uniform model' the correct choice.

measures the likelihood of a chance event occurring

• outcomes

• event

• probability

• uniform model

Answer explanation

Probability measures the likelihood of a chance event occurring, making it the correct choice. Outcomes refer to results, events are occurrences, and a uniform model describes a specific type of probability distribution.

the possible results of an experiment

• event

• probabilities

• probability

• outcomes

Answer explanation

In an experiment, the possible results are referred to as outcomes. While probabilities relate to the likelihood of these outcomes, the term 'outcomes' specifically denotes the actual results that can occur.

a way to find the total number of possible outcomes using multiplication

• theoretical probability

• experimental probability

• complementary events

• fundamental counting principal

Answer explanation

The fundamental counting principle states that if there are multiple ways to perform different tasks, the total number of outcomes is found by multiplying the number of ways for each task. This is the correct choice.

What actually occurs based on repeated trials

• experimental probability

• event

• sample space

• theoretical probability

Answer explanation

Experimental probability is determined by conducting repeated trials and observing the outcomes. It reflects what actually occurs in practice, unlike theoretical probability, which is based on expected outcomes.

something that occurs

• sample space

• outcomes

• probability

• event

Answer explanation

An 'event' is defined as something that occurs within a sample space, making it the correct choice. Outcomes are the results of an event, while probability measures the likelihood of an event happening.

each outcome has the same probability of occurring

• pipe model

• normal model

• uniform model

• short pipe model

Answer explanation

The uniform model is characterized by each outcome having the same probability of occurring, making it the correct choice. Other models, like the normal model, do not have this property.

the set of all possible outcomes

• sample space

• compound event

• experimental probability

• event

Answer explanation

The set of all possible outcomes in a probability experiment is called the sample space. It encompasses every potential result, making 'sample space' the correct choice over other options like compound event or experimental probability.

what should occur or what we expect to happen

• sample space

• theoretical probability

• event

• uniform model

Answer explanation

Theoretical probability refers to what we expect to happen in an event based on mathematical reasoning, making it the correct choice. It contrasts with experimental probability, which is based on actual experiments.

two or more simple events

• experimental probability

• sample space

• compound event

• probability

Answer explanation

A compound event consists of two or more simple events combined. This distinguishes it from a single event or the overall sample space, making 'compound event' the correct choice.
