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.
