To find the joint relative frequency of being female and attending a drama movie, we need to determine the proportion of the total number of viewers who match both of these criteria.

Here is the step-by-step process:

1. Identify the number of females who attended a drama movie: According to the table, 151 females attended a drama movie.

2. Identify the total number of viewers: The total number of viewers is 479.

3. Calculate the joint relative frequency: The joint relative frequency is the ratio of females who attended a drama movie to the total number of viewers. This is given by dividing the number of females who attended a drama movie by the total number of viewers.

Thus, we divide 151 by 479, resulting in a joint relative frequency of approximately 0.31524008350730687.

Therefore, the correct answer is:
C. Divide 151 by 479.
