Dating age formula xkcd
Each straight couple needs to include one of the x males and one of the n-x females so there are x n-x possible ways of combining one of each.
Each gay couple needs to include either two males or two females. To choose two males, we can start with any of the x males and choose any of the x-1 remaining males. However, that counts each possible pairing twice.
To avoid double counting the possible couples, we therefore need to divide that total by 2. As a worked example, for Firefly, of the 9 principal cast, 5 are men and 4 are women.
If all were gay, there would be 16 possible hook-ups; if all were straight, there would be There is a typo in his formula for gay casts. Notice the x-n term.
This also the small implication that "Queer as Folk" was so dull that Randall produced this equation to occupy his mind during it. I often find my mind wandering while sat watching soaps with my other half. The first equation can also be understood more simply as the total number of possible pairings, minus the number of straight ones. I think all genders being constant isn't really an assumption of the graph.
Obviously the graph only works for a single moment in time in a TV show, since the cast changes over time with the plot of the show such as when people die in the show.
The graph already needs to be re-drawn every time someone enters or leaves the cast. For the data we're tracking, a sex change operation is the same as, for example, a man leaving the show and a woman subsequently entering it. Sure, you could then also say that the cast being constant is an assumption of the graph, but that's not really accurate either.onthorwatu.cf

The graph simply doesn't observe the passage of time. You'd have to add a time axis for that, making the graph three-dimensional. I think a better way to explain the gay pairing equation would be to look at it like this: Then substract x n-x which is the equation for all straight pairings. Hope I'm editing correctly. It actually comes out that if each individual's gender is chosen randomly, the expected value for straight casts and for gay casts is the same not too hard to prove via induction.
It's 'cause you're dumb. Real-life prospective-pairing curves over things like age can get depressing. Explanation [ edit ] The equations in the comic and the graph show how many different love pairs can be made if you know the number of females and males in a group.

Formulas [ edit ] The formulas may be derived as follows: Equations and links to wolfram-alpha [ edit ] Formula for Gay pairing: Assumptions [ edit ] The chart and the calculations assume that: No one is bisexual, asexual, polyamorous, celibate, or of some other sexuality. The Half Plus Seven Rule is an unwritten rule that asserts that it is creepy to date anyone who is younger than half your age plus 7 years. As the graph shows, there is a lower limit and an upper limit.
As age increases, the age range of potential non-creepy partners widens. At 26, the range of non-creepy partners is 18 years to year-olds. At 50, it is 54 years 32 to 86 years old.

At age 14, you can only date people your own age. The same also works with infinity, but even Methuselah died once. While the application of this rule actually reduces the number of potential matches further, Cueball presents it in a positive way. By showing that there are whole swathes of people who she couldn't marry in the first place without being in a creepy relationship, and that as her age increases, the range of non-creepy partners increases, combined with Census Bureau data, Cueball shows that her eligible dating pool is in fact still increasing.
Megan notes that graph-making nerds like Cueball may have a hard time finding dates, but this is refuted by the title text.
