[...] So, the optimal strategy, according to mathematics, is to let 37% of the first candidates pass, then choose the first one who is better than all the previous ones. III - Making the couple last Finally, now that we have met someone and are with the right person, the goal is for the relationship to last. Once we have met the right person, the challenge is to build a relationship that lasts. And surprisingly, mathematics can still help us. Let's take the example of the dating app OkCupid. [...]
[...] On the contrary, mathematics studies models, and life itself often follows models like the weather, financial markets . or even our amorous choices. She explains that falling in love is not just a matter of chance, but also of strategy. One of the most well-known mathematical approaches to this topic is what is called the secretary problem. Here is the principle: you must choose the best possible option in a series of choices, without being able to go back. It's as if, in the course of your life, you met several potential partners, but you had to decide on the spot whether you would commit . [...]
[...] We are then looking for the number of groups of 3 people out of 20, without order, which is the combination formula. We calculate 3 out of 20 (binomial coefficient) which gives us 1140 possible combinations to get to know different people. So, in this situation, we can see that mathematics can help us realize the scope of possibilities since, despite the small number of people, the number of combinations is immense. In addition, we can also use an arrangement, that is, where order counts, since on dating sites, the order of display counts. [...]
[...] Thus, thanks to probabilities, statistics, and algorithms, mathematics offers concrete tools for creating solid and lasting relationships." Conclusion : In this way, we have seen that mathematics can be used to shed light on complex subjects such as love. We can use mathematical tools at each stage of the relationship: meeting, choosing the person and keeping a stable couple. However, it is essential to note that mathematics does not replace emotions and feelings in a love story, but can offer a different perspective on the subject. [...]
[...] We can then calculate the probability of meeting at least one compatible person by testing 15 profiles at random. Indeed, we repeat the same experiment 15 times in an independent and identical manner. Each experiment admits only 2 outcomes: meeting a compatible person who is the success with a probability of 0.10 or meeting an incompatible person who is the failure with a probability of 0.90. We set a random variable numerical value to each possible outcome of a random experiment), which counts the number of successes, follows a binomial distribution of order n=15 and parameter p=0.10.
