When doing blood testing for a viral infection, the procedure can be made more efficient and less expensive by combining partial samples of different blood specimens. If samples from three people are combined and the mixture tests negative, we know that all three individual samples are negative. Find the probability of a positive result for three samples combined into one mixture, assuming the probability of an individual blood sample testing positive for the virus is 0.03.

Answer:
The best way to approach this type of problem is to use the "complement method" ...
P(positive result) = 1 - P(negative result)
= 1 - (1 - 0.03)^3
= 1 - 0.97^3 = 0.087327 or 8.7%
Explanation:
Answer:
Explanation:
Given -
Probability of positive blood sample for an individual is equal to 0.03
Number of sample is equal to three
Now , probability of getting a positive result for three sample combined into one single mixture is equal to
where P represents the probability of getting all individual negative test result
Substituting the given values in above equation, we get

Answer:
Anthropoids lived for approximately 0.86% of the total time.
Explanation:
Anthropoids are the higher developed organisms that includes apes and ape mans. The age of earth is 3500 million and anthropoids lived for about 30 million years. By the simple calculations we can find out the data in percent which gives us the result nearest to 0.86%. That means 0.86% of 3.5 billion year is equivalent to 30 million years (time that was lived by anthropoids).
