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 only test negative if all the individual samples are negative. If the probability that an individual sample tests positive is 0.11, what is the probability that the mixture will test positive?

b. 0.00000177
c. 1.00
d. 0.497

A: you can find this by finding the complement, that being if all of the blood samples were negative, and then subtracting that from one. The probability of one blood sample testing negative is 0.89, raising that to the 6th power due to the 6 blood samples gives us about 0.497, and subtracting that from one gives us a, 0.503.
