That is very hard to asses. I prefer to look it like this, what chances is that you will find a partner (like for marry to) out of 100 or so. I do believe, if given equal chance of interaction, you could find a marrying-material partner every 7 or 8 people. Now, in a world of plenty of choices, biases etc, we shuffle through hundreds of people before settling with one… and, even then, still unhappy with the choice for the people we haven gone through yet in our search. Now, that is for me… Chances is you would choose a different person out of these very same 7 to 8 people. Both chosen persons have the same chance of being equally good persons, as the non chosen ones.
