Probability of malaria

A survey at a hospital indicates that the probability of a patient testing positive for malaria is 0.6. Two patients are selected at random. What is the probability that:
(i) one tests negative and the other tests positive?
(ii) both patients test positive?

Final Answer:

p1 =  0.48
p2 =  0.36

Step-by-step explanation:

p=0.6  C1(2)=(12)=1!(21)!2!=12=2  p1=(12) p (1p)=2 0.6 (10.6)=0.48
p2=p2=0.62=0.36
