M2 3.1.1 Probability - Intersections Unions and Complements

Front

What are two events that have the same chance of occurring?

Back

Equally Likely

Front

What does the term 'union' represent in probability?

Back

The combination of two events occurring, denoted as A ∪ B.

Front

What does the shaded region in a Venn diagram typically represent when it shows A and B?

Back

A and B (the intersection of both events).

Front

What type of set is denoted as either { } or ∅?

Back

Empty (or Null) Set.

Front

What is the probability of the intersection of two events, Pizza and Water, denoted as P(Pizza ∩ Water)?

Back

58/400.

Front

What is the definition of a sample space in probability?

Back

The set of all possible outcomes of a probability experiment.

Front

What does the complement of an event A represent?

Back

All outcomes in the sample space that are not in A, denoted as A'.

Front

What is the formula for calculating the probability of the union of two events A and B?

Back

P(A ∪ B) = P(A) + P(B) - P(A ∩ B).

Front

What is a universal set in probability?

Back

The set that contains all possible outcomes for a particular situation.

Front

What does the term 'disjointed sets' mean?

Back

Two sets that have no elements in common; their intersection is empty.
