The answer is <em>X</em>= 15/19
The mixture will test negative if the 6 individuall samples are negative.
Ther probability that one sample is negative is independent of the probabilities of the other samples.
Then, the probability of the six combined events (all negative) is equal to the product of the probabilities for each sample (each negative).
The probability for one sample to be negative is 1 - 0.11 = 0.89.
Then, the combined probability is [0.89]^ 6 = 0.497 ≈ 0.50
