In 2013, a man was arrested for transporting 400 pounds of marijuana across state lines.His DNA was tested, entered into the CODIS database, and found to match the crime scene sample in a murder case (see Table) .
$$\begin{array} { | l | c | c | } \hline & \text { Crime scene sample } & \text { Suspect 1 } \\\hline \text { SSR locus } 1 & 10,10 & 10,10 \\\hline \text { SSR locus } 2 & 11,11 & 11,11 \\\hline \text { SSR locus 3 } & 6,9 & 6,9 \\\hline\end{array}$$
-In a group of 100,000 people, about how many would be expected to have the same genotype as the crime scene sample? For simplicity, assume all SSR alleles are present in the population at a frequency of 0.2.

A) 0.000256
B) 6
