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?

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...

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.

Thus, the meaning of A1∪A2 is at least one parent has the disease influenza.
