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)

A conditional Probability: P(A | B) is asking what is the probability we get event A if we know that event B occurred. A useful formula: P (A | B) = ||| P(A and B) P(B) Or: P(A | B) = (remaining # of ways to get A) / (remaining number of possible outcomes) A bag has 5 red balls, 7 green balls, and 8 purple balls. Two balls are going to be selected. After the first ball is drawn it is NOT returned to the bag. Find the probability the second is a red ball if you know the first chosen is a red ball. If A = event a red ball is selected: P(A|A) = ?
