InformationUse the following information to answer Questions 5 through 9.You are a forensic scientist and you are able to obtain the following 3 CODIS STRgenotypes from an evidence sample found at a crime scene:LocusEvidence GenotypeTH015,5TPOX16,17vWA10,11A reference sample from a suspect has the same exact genotypes as the evidencesample. Using the database table of genotype frequencies below and the genotypesof the evidence sample, answer the following questions. Calculate the probability thatthe genotypes from the evidence sample found at the crime scene and the referencesample from the suspect are from 2 different individuals but coincidentally matchedby chance.IndividualTHO1TPOXvWA15,516,1610,1023,716,1710,1233,416,1513,1445,514,1711,1254,417,1711,1164,817,1710,1077,819,1910,1289,918,1914,1493,615,1513,14
