Probability & Venn Diagrams

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 is a Venn Diagram?

Back

A Venn Diagram is a visual representation of the relationships between different sets, often used to illustrate the overlap between them.

Front

How do you calculate the probability of an event?

Back

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

Front

What does it mean if the probability of an event is 0.5?

Back

It means there is an equal chance of the event occurring or not occurring.

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 independent event?

Back

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

Front

What is a dependent event?

Back

Two events are dependent if the occurrence of one event affects the probability of the other event occurring.

Front

How do you find the probability of two independent events occurring together?

Back

Multiply the probabilities of each event: P(A and B) = P(A) * P(B).

Front

What is the union of two sets in a Venn Diagram?

Back

The union of two sets is the set of elements that are in either set or in both sets.

Front

What is the intersection of two sets in a Venn Diagram?

Back

The intersection of two sets is the set of elements that are common to both sets.
