Making Predictions with Probability

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What does a probability of 0 mean?

Back

A probability of 0 means that the event will not occur.

Front

What does a probability of 1 mean?

Back

A probability of 1 means that the event is certain to occur.

Front

How do you calculate the probability of an event?

Back

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

Front

What is a favorable outcome in probability?

Back

A favorable outcome is an outcome that satisfies the condition of the event we are interested in.

Front

What is the sample space in probability?

Back

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

Front

What is an event in probability?

Back

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

Front

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.

Front

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

Back

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

Front

If you flip a coin, what is the probability of getting heads?

Back

The probability is 1/2, as there are two possible outcomes (heads or tails) and one favorable outcome (heads).
