What is a probability model?

Back

A probability model is a mathematical representation of a random phenomenon, describing the likelihood of different outcomes.

Front

What is a sample space?

Back

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

What does it mean to draw a marker without looking?

Back

It means selecting a marker randomly from a collection without any visual guidance, ensuring each marker has an equal chance of being chosen.

Front

How do you calculate the probability of an event?

Back

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

Front

What is an even number?

Back

An even number is an integer that is exactly divisible by 2.

Front

If there are 5 blue markers and 3 red markers, what is the probability of picking a blue marker?

Back

Probability = 5/(5+3) = 5/8.

Front

What is the difference between an event and a sample space?

Back

An event is a specific outcome or a set of outcomes from the sample space.

Front

What does it mean if an event is certain?

Back

If an event is certain, it has a probability of 1, meaning it will definitely occur.

Front

What is the probability of rolling a 3 on a standard six-sided die?

Back

Probability = 1/6, since there is one favorable outcome (rolling a 3) out of six possible outcomes.

Front

What is a random experiment?

Back

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