I am not the best stats person and I don't have the final answer. However, 

"There has been found a DNA of type S on a crime scene.M = 50 individuals in the whole population that have a DNA of type S.
Assume that every individual in the population have the same likelihood of being a contributor. Assume there is a DNA-database consisting of n = 30000 individuals. 
Find the probability that the contributor is one of the individuals in the database.
