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 four people
are combined and the mixture tests negative, we know that all four individual samples are
negative. Find the probability of a positive result for four samples combined into one mixture,
assuming the probability of an individual blood sample testing positive for the virus is 0.03. Report
the answer.
