Math 1530 - Chapter 3 Vocab

Cannot happen at the same time (select two answers).

• Mutually Exclusive

• P(A|B) = P(A)

• Complementary

• P(A ∩ B) = 0

Mutually Exclusive Events whose probabilities sum to 1 (select two answers).

• Mutually Exclusive

• Complementary Events

• P(A') = 1 - P(A)

• • P(A|B) = P(A ∩ B)/P(B) 

Use of historical data

• Theoretical Probability

• Subjective Probability

• • Relative frequency probability 

• Conditional Probability

Where the real frequency behavior of a system converges with the theoretical behavior.

• • Theoretical probability

• Probability

• Sampling with Replacement

• Relative frequency probability

When we know exactly how the "system" behaves we use pure math.

• Equally Likely Events

• • Theoretical probability

• Relative frequency probability

• Probability

Collections of Outcomes.

• Events

• Outcomes

• Sampling with Replacement

• Probability

Restricts the orignial sample space; A given B (select two answers).

• • P(A|B) = P(A ∩ B)/P(B) 

• Complementary Events

• Conditional Probability

• P(A U B) = P(A) + P(B) – P(A ∩ B)

When each member of the population has an [blank] chance to be chose.

• Equally Likely Events

• Independent Events

• Outcome

• Dependent Events

Is a special type of graph used to determine the outcomes of an experiment. It consists of "branches" that are labeled with either frequencies or probabilities.

• Venn diagram

• Trend

• Tree Diagram

• Random Events Diagram

A planned operation carries out under controlled conditions.
