Question 1064199: Samples of spinal fluids are routinely tested for the presence of tuberculosis (TB) and bacteria. Suppose that 80% of the samples attest negative for both TB and bacteria. What is the probability that a random sample tests positive for either TB or bacteria? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Samples of spinal fluids are routinely tested for the presence of tuberculosis (TB) and bacteria. Suppose that 80% of the samples attest negative for both TB and bacteria. What is the probability that a random sample tests positive for either TB or bacteria?
-------
P(TB or bact) + P(not TB or bact) = 1
P(TB or bact) = 1-0.8 = 0.2
