english: The average lottery buyer buys about 150 tickets a year, so the buyer knows full well that he or she is going to lose, and yet she buys 150 tickets a year. Why is that?
non_english: De gemiddelde loterij-deelnemer  koopt zo’n 150 loten per jaar, dus de speler weet zelf goed  dat hij of zij zal verliezen, maar koopt toch 150 loten per jaar.
