Dit is correct. Als we tossen met een muntstuk hebben we 50% kans dat het kop is en 50% kans dat het munt is. Daarom weet je niet hoe de bovenste grafiek zal verlopen. De beste voorstpelling die we kunnen doen is de lijn doortrekken naar het midden.
Hier zien we geen seizonaliteit maar er is wel een trend.
