Your answer is most likely A. Use media
Answer:
The probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.964
If the survey subjects <em>volunteered</em> to respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a <em>response bias.</em>
Explanation:
Let P(at least one is more careful about personal information when using a public Wi-Fi hotspot) denote the probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot, then we have the equation
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot)
- If 67% of Internet users are more careful about personal information when using a public Wi-Fi, then 33% of them are not.
P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot) = ≈ 0.036
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - 0.036 = 0.964
The purpose of including multiple layers in your network security<span> is to make sure that </span>each single defense component has a backup<span> in the case of a flaw or missing coverage. The individual strengths of each layer also cover any gaps that other defenses may lack.</span>
With this assumption in mind, each individual layer in a multi-layered security approach focuses on a specific area where the malware could attack. By working in concert, these layers of security offer a better chance of stopping intruders from breaching company networks than using a single solution.
The types of security layers you can use in your network defense include:
<span>
Web protectionPatch managementEmail security and archivingVulnerability assessment and analyticsAntivirus softwareData encryptionFirewallsDigital certificatesAnti-spam and spam filtersPrivacy controls</span>
<span>Having multiple layers of security in place is crucial for MSPs who protect data at all levels and across numerous applications and devices. Not only should data stay safe, but so should the methods of communication and the network where information is transferred.</span>
