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
You can make a hierarchical directory structure under /root that
consists of one directory containing subdirectories by using cd and
mkdir
the mkdir command created the directories while the cd command changes which directory you're currently in
Import java.util.Scanner;
class hola
{
public static void main(String[]args)
{
Scanner x=new Scanner(System.in);
int a=x.nextInt();
int b;
if(a>20&&a<100)
{
b=a%12;
if(b%2==0){
System.out.print("es par"+b);
}
else{
System.out.print("es impar"+b);
}
}
}
}
import math
print(math.pow(8, 0.5))
You can find the square root of any number by squaring it by 0.5
