The probability for this locus can be calculated in the same way as for a single source sample via the random match probability. Using the same approach, the additional loci will be evaluated.

A typical statement would be the following: The probability of randomly selecting an unrelated individual from the U.S. population who could not be excluded as a contributor to the mixed sample is estimated to be 1 in 2 million.*

* This number used arbitrarily for this example.
