Question: A certain herb is grown in three places on Earth. It is known that this herb has medicinal value in treating certain illnesses, but that sometimes it is fatal. In the accompanying table, column two gives the percent of the total herb production of the world that is grown in that location, and the third column gives a percent of the herb from that location that is fatal.
% of Total Percent Fatal
Lower Amazon 62 14
Sub-Saharan Africa 25 6
Newark, New Jersey 13 1/2
For each location, calculate the probability that a sample of the herb came from that location, if it was found to be fatal.
