he probability of a randomly selected adult in one country being infected with a certain virus is
0.003.

In tests for the​ virus, blood samples from
14

people are combined. What is the probability that the combined sample tests positive for the​ virus? Is it unlikely for such a combined sample to test​ positive? Note that the combined sample tests positive if at least one person has the virus.










The probability that the combined sample will test positive is

​(Round to three decimal places as​ needed.)

Is it unlikely for such a combined sample to test​ positive?







A.


It
is

unlikely for such a combined sample to test​ positive, because the probability that the combined sample will test positive is
greater than

0.05.






B.


It
is

unlikely for such a combined sample to test​ positive, because the probability that the combined sample will test positive is
less than or equal to

0.05.






C.


It
is not

unlikely for such a combined sample to test​ positive, because the probability that the combined sample will test positive is
greater than

0.05.






D.


It
is not

unlikely for such a combined sample to test​ positive, because the probability that the combined sample will test positive is
less than or equal to

0.05.
