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

step-by-step explanation:

a

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
