Information
Use the following information to answer Questions 5 through 9.
You are a forensic scientist and you are able to obtain the following 3 CODIS STR genotypes from an evidence sample
found at a crime scene:
Locus Evidence Genotype
TH01 5,5
TPOX 16,17
vWA 10,11
A reference sample from a suspect has the same exact genotypes as the evidence sample. Using the database table of
genotypes below and the genotypes of the evidence sample, answer the following questions. Calculate the probability
that the genotypes from the evidence sample found at the crime scene and the reference sample from the suspect are
from 2 different individuals but coincidentally matched by chance.
