Er zijn ook geen patronen van het verleden die ons in staat stellen voor voorspellingen te doen = dit experiment is onafhankelijk van het verleden en zal dus niet convergeren naar een horizontale lijn (2e grafiek).

Goede verklaring.

Goed, zoals hierboven vermeld, ook de 2de grafiek is onafhankelijk van het verleden, de patronen zijn puur toeval, omdat de munt, zo gezegd, niet weet wat ervoor gegooid is.

Q1: De conclusie en uitleg zijn correct en uitgebreid , enkel de student zegt dat de experiment we afhankelijk is van het verleden wat niet het geval is , elke worp is totaal onafhankelijk van de voorgaande.
