Explanation:
The essence of what is a Relative Frequency Distribution is to devide the frequency of an event (in this case "the times that males spend each day thinking about females") by the total number of cases to get the % of how often the event occurs.
In this case, as example:
Say your distribution looks like this:
"the times that males spend each day thinking about females" : 10
"the times that males doesn't spend each day thinking about females": 15
"total" : 25
Relative Frequency Distribution
"the times that males spend each day thinking about females" : 10/25 = 0.4
"the times that males doesn't spend each day thinking about females": 15/25 = 0.6
"total" : 25/25 = 1
0.4 + 0.6 = 1
You can conclude from this that 40% is the times that males spend each day thinking about females
