“According to the examiner in his letter of July 7th 2000, the probability that the blood on the piece of glass came from someone other than the suspect is smaller than 1:53.000.000. This conclusion forms the basis for the Court’s conviction that the suspect and not a third committed the robbery.”

“The probability for a random individual to have the same DNA-profile as the one found in the examined blood on the piece of glass ABG758, is much less than one in a million.
The current number obtained statistically from our reference database of white Dutch people is one in 53 million.”

In the next slides select (part) of the observation or hypothesis words, then click the corresponding button. You will get feedback and colors will indicate the right answer. Then choose if this would be a right or wrong statement for an examiner to make.

For a DNA-profile you can precisely calculate the probability that it came from a random person: the ‘random match probability’.

The probability that a random person has the same DNA-profile as the trace from the crime scene is smaller than 1 in a billion.

Deze temperatuur van het overleden slachtoffer is waarschijnlijker wanneer deze overleed op het tijdstip van het scenario van de verdediging, dan op het tijdstip van de aanklager.

We zagen overeenkomsten in de werktuigsporen, waardoor het iets waarschijnlijker is dat de sporen van de schroevendraaier van de verdachte kwamen dan van een andere schroevendraaier.

Omdat de chromatogrammen erg op elkaar lijken, is het waarschijnlijker dat de benzine waarmee de brand is gesticht uit de jerrycan van de verdachte kwam, en niet van een andere bron.
