5359 pregnant women were tested to see if their babies had Down Syndrome (D). The results of the test are given in the table. 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. Yes, because P(NEG|D) deals with a much smaller pool of fetuses than P(D|NEG)

By rewriting the formula for the multiplication rule, you can write a formula for finding P(A and B) conditional probabilities. The conditional probability of event B occurring, given that event A has occurred, is P(B A) = Use the information below to find the probability that a flight P(A) departed on time given that it arrives on time. The probability that an airplane flight departs on time is 0.89. The probability that a flight arrives on time is 0.87. The probability that a flight departs and arrives on time is 0.83. The probability that a flight departed on time given that it arrives on time is (Round to the nearest thousandth as needed.)
