In a blood testing procedure, blood samples from 4 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 0.08, what is the probability that the mixture will test positive?

 0.2836071

Step-by-step explanation:

Given : In a blood testing procedure, blood samples from 4 people are combined into one mixture.

Probability that an individual sample tests positive = 0.08

Then ,  Probability that an individual sample tests negative= 1-0.08=0.92

Since , the  mixture will only test negative if all the individual samples are negative.

Then, the probability that the mixture will test positive = 1- P(all test negative)

Hence , the probability that the mixture will test positive = 0.2836071
