Use the values in the table to answer parts a-c. a. Given that a test result is negative (NEG), what is the probability that the fetus actually has Down syndrome? P(D|NEG)= b. Given that the fetus has Down syndrome, what is the probability that the test result is negative? P(NEG|D)= c. Is P(D|NEG) equalt to P(NEG|D)? A. Yes, because P(NEG|D) deals with a much larger pool of fetuses than P(D|NEG). B. No, because P(NEG|D) deals with a much smaller pool of fetuses than P(D|NEG). C. No, because P(NEG|D) deals with a much larger pool of fetuses than P(D|NEG). D.
