Is below correct?

Testing for a disease can be made more efcient by combining samples. It the samples trom three people are combined and the mixture tests negative, then all three samples are negative On the other hand, one positive sample Will always test positive, no matter how many negative samples it is mixed With. Assuming the probability ot a Single sample testing posmve is 0.2, nd the probability of a positive result for three samples combined into one mixture. Is the probability low enough so that further testing ot the indivutual samples is rarely necessary? The probability of a positive test result is 0 488 (Round to three decimal places as needed ) Is the probability low enough so that further testing of the individual samples is rarely necessary? A. The probability is not low, so further testing of the individual samples WIII hequently be a necessary event. 0 E. The probability is low, so furlher testing Will be necessary for all of the combined mixtures. O C. The probability is not low, so further testing will not be necessary for any otthe mixtures O D. The probability is low, so furlher testing at the individual samples Will be a rarely necessary event
