A is the answer to your question
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).

Answer:
The radius r of the circle is 44cm
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, a circular shape.
Given data
Circumference of circle C= 88πcm
Radius of circle r=?
The problem seeks to solve for the radius r.
To solve for the radius let us apply the formula for the circumference of a circle
C=2πr
Substituting our given data
88π=2πr
Making r subject of formula we have
r= 88π/2π
r= 44cm
