Answer:
from socket import *
hostname = input('Enter the host to be scanned: ')
ip_add = gethostbyname(hostname)
connections = [ ]
for i in range(133, 136):
s = socket(AF_INET, SOCK_STREAM)
conn = s.connect_ex((ip_add, i))
print(conn)
connections.append(conn)
if 0 in connections:
print ('Host is online')
s.close()
else:
print ('system is unreachable')
Explanation:
The python source code above scans for all the available range of ports in the provided hostname, if any port is available, the host is online else the program print the error message "system is unreachable.
Answer: 0.1937
Explanation:
Given : A bowl contains 20 candies; 15 are chocolate and 5 are vanilla.
If we select 5 candies, then the number of ways to select them is given by permutations.
The number of ways to select 5 candies is given by :-
The number of ways of selecting any 5 candies out of 20:-
Now, the probability that all 5 are chocolate :-
Hence, the probability that all 5 are chocolate =0.1937
