Making Predictions with Probability (TASK CARDS)

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, where 0 means the event will not happen and 1 means it will definitely happen.

Front

What is an event in probability?

Back

An event is a specific outcome or a set of outcomes from a probability experiment.

Front

What is the sample space?

Back

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

Front

How do you calculate the probability of a single event?

Back

The probability of a single event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is a favorable outcome?

Back

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

Front

What does it mean for events to be independent?

Back

Two events are independent if the occurrence of one event does not affect the occurrence of the other.

Front

What is a dependent event?

Back

Dependent events are events where the outcome of one event affects the outcome of another event.

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

What is the probability of flipping heads on a fair coin?

Back

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

Front

What is a compound event?

Back

A compound event is an event that involves two or more simple events.
