Finding Probability The crude death rate for Spain was recently 8.3, and that rate was computed using a multiplier of k = 1000.

a. Find the probability that a randomly selected Spaniard died within the year.

b. If two Spaniards are randomly selected, find the probability that they both died within the year, and express the result using three significant digits.

c. If two Spaniards are randomly selected, find the probability that at least one of them survived the year, and express the result using six decimal places. What would be wrong with expressing the answer using three significant digits?
