Consider a family with a mother, father, and two children. Let A₁ = {mother has influenza}, A₂ = {father has influenza}, A₃ = {first child has influenza}, A₄ = {second child has influenza}, B = {at least one child has influenza}, C = {at least one parent has influenza}, and D = {at least one person in the family has influenza}.

3.1 What does A₁ ∪ A₂ mean?

Expert Solution & Answer

To determine

Explain the meaning for A1∪A2.

Explanation of Solution

The events A1 and A2 are defined as given below:

A1 = {mother has influenza}

A2 = {father has influenza}

The union of two events A and B is denoted as A ∪ B is defined as either event A or event B occurs, or both occur. That is, at least one event occurs.
