A test to determine whether a certain antibody is present is 99.1​% effective. This means that the test will accurately come bac
avanturin [10]

Answer:

The probability that all the six people will test negative for the antibody is 0.9472.

The probability that the test comes back positive for at least one of the six ​people is 0.0528

Step-by-step explanation:

Consider the provided information.

probability that antibody is present will be effective is 99.1​% and not present​ is 99.1​% of the time.

Part (A)What is the probability that the test comes back negative for all six ​people? ​

Let P(X)= P(Antibody not present)

We want test comes back negative for all six that means antibody is present for all six. Thus X=0

P(X=0)=0.991\times0.991\times0.991\times0.991\times0.991\times0.991\\P(X=0)=0.9472

The probability that all the six people will test negative for the antibody is 0.9472.

Part (B) What is the probability that the test comes back positive for at least one of the six ​people?

P(X \geq1)=1-P(X=0)

P(X \geq1) = 1-0.9472

P(X \geq1) = 0.0528

Hence, the probability that the test comes back positive for at least one of the six ​people is 0.0528
