Solve this problem based on a poll, 62% of internet users are more careful about personal information when using a public wi-fi hotspot. what is 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? how is the result affected by the additional information that the survey subjects volunteered to respond?

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-

                                          =1-

                                         =1-

                                         =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:

The result should not be impacted by this because volunteers are likely to have the most relevant responds.
