For the various organ transplants performed in the United States in 2003, the probability of surviving for at least a year was 0.98 for kidney transplants, and 0.88 for other transplants.
a. If exactly half of the transplants had been kidneys, what would be the overall probability of surviving for at least a year?
b. In fact, the probability of being a kidney transplant was 0.59. What was the actual overall probability of surviving any transplant for at least a year?
c. If there were approximately 26,000 organ transplants in 2003, about how many patients did not survive for one year?
d. Are 0.98 and 0.88 describing the population or a sample?
e. Should 0.98 and 0.88 be denoted p1 and p2 or and?
