A forensic scientist recovers two bloodstains from the crime scene. Bloodstain 1 is of blood type A and bloodstain 2 is of blood type B. The investigation leads to a person of interest who is of blood type B. Given that the match probability for blood type A is 0.40 and the match probability for blood type B is 0.11, what likelihood ratio do you assign to these results for the following pair of propositions?

H_p:At least one of the bloodstains came from this person of interest.

H_d:Neither of the bloodstains came from this person of interest.

In this likelihood ratio assignment please assume that if proposition is true, then it is a priori equally probable for the person of interest to be the source of bloodstain 1 as it is for the person of interest to be the source of bloodstain 2.

(Please round your answer to 2 digits after the decimal point.)
