The Results From A Test To Detect The Presence Of A Bacteria In A Sample Are Shown In The Table What Is The Probability That The Result Of The Test Is Positive class=

Answer:

It is C because u just divide 126 by 58!!

Step-by-step explanation:

The probability that the result of the test is positive, given that the sample doesn't contain the bacteria = 0.03

What is probability?

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

The formula of the probability of an event A is:

P(A) = n(A) / n(S)

, where n(A) is the number of favorable outcomes and  is the total number of events in the sample space.

For given example,

Let event A : the number of result of the test is positive, given that the sample doesn't contain the bacteria

⇒ (n(A)) = 58

the total number of sample n(S) = 2000

Therefore,  the probability that the result of the test is positive, given that the sample doesn't contain the bacteria would be,

⇒ P(A) = n(A)/n(S)

⇒ P(A) = 58/2000

⇒ P(A) = 29/1000

⇒ P(A) = 0.029

⇒ P(A) = 0.03

Therefore, the correct answer is option (A) 0.03
