In communities with large HIV outbreaks, a heavy majority of recent HIV diagnosis were also diagnosed with hepatitis C. Suppose among a rural community in Ohio, 33% were diagnosed with both HIV and hepatitis C, whereas 40% had neither of these. The probability that someone was diagnosed with HIV is 0.41

What is the probability that a randomly chosen person in this community was diagnosed with hepatitis C? (3 points)

Select one:

a. 0.59

b. 0.08

c. 0.52

d. 0.60

e. 0.43

Q 2

Question 2

What is the probability that a randomly chosen community member is diagnosed with HCV given that s/he does not have HIV? (2 points)

Select one:

a. 0.32

b. 0.41

c. 0.59

d. 0.62

e. 0.38

Q 3

Question 3

Are the events of being diagnosed with HIV and hepatitis C mutually exclusive? (2 points

Select one:

a. They are mutually exclusive because some people have both HIV and hepatitis C, this is shown by P(HIV∩HCV)=0.33 ≠0

b. They are mutually exclusive because people can not have both HIV and hepatitis C, this is shown by P(HIV∩HCV)=0=0

c. They are not mutually exclusive because some people have both HIV and hepatitis C, this is shown by P(HIV∩HCV)=0.33 ≠0

d. They are not mutually exclusive because people can not have both HIV and hepatitis C, this is shown by P(HIV∩HCV)=0=0

e. Cannot be determined from the given information
