uitleg oke! niets aan toe te voegen.

De grafieken hierboven zijn verkregen door toepassing van de random walk simulation.
De schijnbare lange termijn trend die in bovenstaande grafieken waarneembaar is, is
bekomen door puur toeval (er wordt een munt 500 keer opgegooid en gekeken hoeveel
keer deze op kop of munt valt) en is onberekenbaar. Er is ook geen enkele invloed van
seizoenaliteit.

De uitleg is heel goed gegeven, ik leg nog enkel nadruk op de belangrijke dingen
