When an individual is exposed to radiation death may ensue. Factor affecting the outcome are the size of the doze, the length and intensity of exposure and the biological
makeup of the individual. The term LD50 is used to denote the dose that is usually lethal
for 50% of the individuals exposed to it. Assume that in a nuclear accident 30% of the
workers are exposed to the LD50 and die; 40% of the workers die; and 68% are exposed
to the LD50 or die. What is the probability that a randomly selected worker is exposed
to the LD50? Use a Venn diagram to find the probability that a randomly selected
worker is exposed to the LD50 but does not die. Find the probability that a randomly
selected worker is not exposed to LD50 but dies? What is the probability that a
randomly selected worker will die given that he is exposed to lethal dose of radiation?
