n a​ poll, 6767​% of Internet users are more careful about personal information when using a public​ Wi-Fi hotspot. What is the
a_sh-v [17]

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) = 0.33^{3} ≈ 0.036

P(at least one is more careful about personal information when using a public​ Wi-Fi hotspot)  = 1 - 0.036 = 0.964

Which technological tool is important for storing critical files?.
Vanyuwa [196]

The technological tools that can be considered important for storing critical files are battery backup systems and drives. These devices can be used to store data and supply energy.

<h3>Battery backup systems</h3>

A home battery backup system is a device used to keep the electrical system working in the event when the electrical source goes down.

In computation, there are three major classes of batteries systems:  Lead-Acid, Nickel-Cadmium, and Lithium-Ion.

An uninterruptible power supply (UPS) can be considered as a battery backup supply capable of charging when the power is on.
