Nate downloaded a free virus detection program, which reported that his computer is infected with a virus. The editors of a tech
lorasvet [3.4K]

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

\begin{tabular}{lllll}S/N          & Reported & Not reported & Total \\Infected     & 28       & 12   &   40   \\Not Infected & 28       & 36&460\\Total &122&378&500\\\end{table}

Therefore the False Positive can be Mathematically represented as

FP=\frac{94}{122}

FP=0.7705

FP=77.05\%

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
