There is a constant shortage of organ donors in the United States. Fewer people are donating organs and ever more people are on waiting lists. One solution to this problem involves compensating organ donors. A recent poll suggests that 60% of Americans support some form of compensation in terms of future health care for people who make organ donations while alive, for example, kidneys, bone marrow, or liver.51 Suppose four Americans are selected at random.
a. What is the probability that all four support compensation for organ donors?
b. What is the probability that none of the four supports compensation for organ donors?
c. What is the probability that exactly two of the four support compensation for organ donors?
