Kako nas verjetnost zavede

Kolikšna je verjentost, da imata dva učenca, v razredu z 30 učenci, na isti dan rojstni dan?

Večina jih na to odgovori enostavno “nič”. In se potem popravijo v “zelo majhna”.

Pri 30 učencih je verjentost cirka 70% (vir). Presenetljivo?

Pri 23 učencih smo na cirka 50% verjetnosti. Pri skupini 57 oseb smo že na 99%. In pri skupini 365 pridemo jasno do 100%.

Seveda sledi še vprašanje, ali znate to sami izračunati? Ali ste kdaj znali? In kako bi reagirali, če bi takšno nalogo prinesel domov učenec šestega razreda osnovne šole?

“An online survey targeted at Silicon Valley Professionals revealed that an astonishing 50 percent are cycling enthusiasts and follow the local scene.”
