Answer:
0.3726 is the required probability.
Step-by-step explanation:
We are given the following information:
We treat blood sample testing positive for the virus as a success.
P( blood sample testing positive for the virus ) = 0.11
Then the number of blood sample follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 4
We have to evaluate the probability of a positive result for four samples combined into one mixture mean that atleast one of the blood sample must be positive for virus.
0.3726 is the probability of a positive result for four samples combined into one mixture.
The two numbers are -6 and -20
-20 x -6 = 120
-20 + (-6) = -26
