Question
In a criminal case, the DNA profile from the crime scene matches the profile of the suspect. From information from the UK DNA database at the time the crime was committed, we know that this profile occurs with a probability of 1:27 million.State whether each of the following interpretations is true or false.
(a) The evidence is 27 million times more likely if the suspect was the source of the DNA profile than if an unrelated man were the source.Answer : true or false? (b) It is 27 million times more probable that the suspect is the source of the profile than an unrelated man is the source. Answer: true or false? (c) Since there were 27 million men in the UK at the time of the crime, we can conclude that there was no other man in the UK matching this profile. Answer :true or false ? (d) The probability that the profile would be of this type if it had come from someone other than the suspect is 1 in 27 million. True or false?

Explanation / Answer
a)
False,
As 1:27 million gives the probability that the sample is of the suspect.
b)
True
It is 27 million times more probable that the suspect is the source of the profile than an unrelated source
c)
False
If there are 27 million people in UK it is probable that suspect is the man who committed the crime but we can't say surely. it has highest probability
d)
True
Yes, the probability that the profile would be of type belong to someone else is 1 in 27 million.
