When an individual is exposed to radiation, death may ensue. Factors affecting the outcome are the size of the dose, the length and intensity of the exposure, and the biological makeup of the individual. The term L1350 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 LDso 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 the LD50 but dies.
