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
Answer:
import sys
import turtle
import random
def n_pointed_star(total_points):
if total_points <= 4:
raise ValueError('Not enough total_points')
area = 150
for coprime in range(total_points//2, 1, -1):
if greatest_common_divisor(total_points, coprime) == 1:
start = turtle.position()
for _ in range(total_points):
turtle.forward(area)
turtle.left(360.0 / total_points * coprime)
turtle.setposition(start)
return
def greatest_common_divisor(a, b):
while b != 0:
a, b = b, a % b
return a
turtle.reset()
n_pointed_star(5)
Explanation:
- Inside the n_pointed_star function, check whether the total no. of points are less than or equal to 4 and then throw an exception.
- Loop through the total_points variable and check whether the result from greatest_common_divisor is equal to 1 or not and then set the starting position of turtle and move it.
- Create the greatest_common_divisor which takes two parameters a and b to find the GCD.
- Finally reset the turtle and call the n_pointed_star function.
Answer:
An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.
