From the question we are told that:
Sample size n=500
Know Virus infection r=8\%
The data can be represented in the Table below a
Therefore the False Positive can be Mathematically represented as
In conclusion we can say that The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%
Therefore
Option B is correct

For 6 systems with exactly 3 failures, you need to calculate 6 pick 3 or 6!/(3!3!) = 720/(6*6)=720/36=20 different combinations of 3 systems to fail. Now the probability of each of those failures will be the probability of the subsystems not failing times the probability of the subsystems fail. So 0.95^3 * 0.05^3 for 3 subsystem not failing time 3 subsystems failing. So 0.95^3 * 0.05^3 = 0.857375*0.000125 = 0.000107172. And multiply by the 6 pick 3 calculated earlier, gives.
0.000107172 * 20 = 0.002143438
And rounding to the nearest thousandth, gives 0.002</span>
Just a guess! Since he was paid $8 less, it is fair to assume the CD was worth $8.
Answer:
Step-by-step explanation:
When multiplying two fractions, you multiply across always. We have two fractions :
7/9 and 5/6
So multiply across :
