To determine the joint relative frequency of being male and attending a drama movie, you need to follow these steps:
1. Identify the number of males who attended a drama movie.
2. Identify the total number of people who attended a drama movie.
3. Divide the number of males who attended a drama movie by the total number of people who attended a drama movie.
Let's break it down step-by-step using the provided table:
1. Number of males who attended a drama movie:
According to the table, there were 124 males who attended a drama movie.
2. Total number of people who attended a drama movie:
The total number of people who attended a drama movie, as shown in the table, is 275.
3. Calculating the joint relative frequency:
To find the joint relative frequency, we divide the number of males who attended a drama movie by the total number of people who attended a drama movie:
[tex]\[
\text{Joint Relative Frequency} = \frac{\text{Number of males who attended a drama movie}}{\text{Total number of people who attended a drama movie}}
\][/tex]
Substituting the numbers from the table, we get:
[tex]\[
\text{Joint Relative Frequency} = \frac{124}{275}
\][/tex]
Upon calculation, this results in:
[tex]\[
\frac{124}{275} \approx 0.4509
\][/tex]
Therefore, the correct choice that represents the joint relative frequency of being male and attending a drama movie is:
C. Divide 124 by 275.
