In a blood testing procedure blood samples from 6 people are combined into one mixture. The mixture will only test negative if all the individual samples are negative. If the probability that an indiv?

If the probability that an individual sample is negative is ( p ), then the probability that all 6 samples are negative (and thus the mixture tests negative) is ( p^6 ). Conversely, the probability that at least one sample is positive (and thus the mixture tests positive) is ( 1 - p^6 ). Therefore, the outcome of the mixture test depends significantly on the value of ( p ).
