Find the indicated probability. Round to the nearest thousandth. In a blood testing procedure, blood samples from 6 people are combined into one mixture. The mixture will test neg if all samples are neg. If the probability that an individual sample tests positive is 0.11, what is the probability that the sample will test ?

Question

hoblos · Answer

probability that an individual sample tests positive is 0.11
so probability that an individual sample tests negative is 1-0.11=0.89

probability that the sample will test negative = [(0.89)^6 ] 
                                                                 = 0.497
