Answer
The probability that among four randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.979.
Step-by-step explanation:
Since 62% of Internet users are more careful about personal information when using a public Wi-Fi hotspot.
Therefore, the Probability of 62% of Internet users are more careful about personal information when using a public Wi-Fi hotspot is, p=0.62.
We have to find the probability that at least one user is more careful about personal information when using wi-fi hotspot.
Probability of internet users are not more careful about personal information when using a public wi-fi hotspot, i.e
Use Binomial Distribution, i.e,
p=0.62, q=0.38, n=4.
Required Probability
or

=1-0.02085136=0.97914864
Therefore, the probability that at least one users more careful about personal information when using wi-fi hotspot, i.e 0.979(approx).
RESULT:
<u>The result should not be impacted by this because volunteers are likely to have the most relevant responds.</u>
