You are considering five different DNA probes for use in a DNA fingerprinting analysis. Shown below is a table illustrating the statistical certainty of obtaining a matching pattern when each probe is used with DNA samples from a certain population. If all five probes are used to type DNA samples from two different sources, what is the probability that an exact match between two samples is due to chance? (show your calculation)

Probe #           Certainty of match

P1                  .02

P2                 .03

P3                  .04

P4                  .05

P5                  .01

Solution

P1 - 0.01

P2 - 0.04

P3 - 0.05

P4 - 0.03

P5 - 0.02

these are posbilities of those five persons of DNA given
