To find the joint relative frequency of being female and attending a drama movie, follow these steps:
1. Identify the specific subgroup of interest. We want the number of females who attended the drama movie, which is given as 151 in the table.
2. Determine the overall total number of people. According to the table, the total number of individuals who attended either movie is 479.
3. Calculate the joint relative frequency. This is done by dividing the number of females who attended the drama movie by the total number of movie attendees.
[tex]\[ \text{Joint Relative Frequency} = \frac{\text{Number of Females attending Drama}}{\text{Total Number of Attendees}} = \frac{151}{479} \][/tex]
4. Perform the division. When you divide 151 by 479, you get approximately 0.315.
Therefore, given these steps, the correct answer is:
[tex]\[ \boxed{D. \divide 151 \text{ by } 479.} \][/tex]
