To find the joint relative frequency of being female and attending a drama movie, you need to divide the number of females who attended the drama movie by the total number of attendees.
Looking at the table:
- The number of females who attended the drama movie is 151.
- The total number of attendees (both males and females, for both movie types) is 479.
Therefore, the joint relative frequency is calculated by dividing the number of females who attended the drama movie (151) by the total number of attendees (479).
So, the correct calculation is:
[tex]\[ \frac{151}{479} \][/tex]
After performing this division, you get:
[tex]\[ 0.31524008350730687 \][/tex]
Thus, the answer is [tex]\( A. \text{Divide 151 by 479} \)[/tex].
