Option c is correct. Node.insertBefore(new, child) is the method that includes or embeds a new node directly ahead of a child node.
The Node interface's insertBefore() method places a node as a child of a given parent node ahead of a reference node.
InsertBefore() transfers the specified node to the new place if it already exists in the document. (That is, before adding it to the given new parent, it will automatically remove it from its current parent.)
As a result, a node cannot be present in two places in the document at once. The full contents of the DocumentFragment are moved into the child list of the chosen parent node if the given child is a DocumentFragment. the node that newNode is added before. In the event that this is null, newNode is appended to the end of the node's child nodes.

Hello, I desperately need help in python with this question. I have tried everything: This is the question also:
4.24 LAB: Even/odd values in a list
Write a program that reads a list of integers, and outputs whether the list contains all even numbers, odd numbers, or neither. The input begins with an integer indicating the number of integers in the list. The first integer is not in the list.
Ex: If the input is:
5
2
4
6
8
10
the output is:
all even
Ex: If the input is:
5
1
-3
5
-7
9
the output is:
all odd
Ex: If the input is:
5
1
2
3
4
5
the output is:
not even or odd
Your program must define and call the following two functions. is_list_even() returns true if all integers in the list are even and false otherwise. is_list_odd() returns true if all integers in the list are odd and false otherwise.
def is_list_even(my_list)
def is_list_odd(my_list)
This is what I came up with:
def GetUserValues():
n = int(input())
numbers = []
for i in range(n):
numbers.append(int(input()))
return numbers
def IsListEven(myList):
for n in myList:
if n % 2 == 1:
return False
return True
def IsListOdd(myList):
for n in myList:
if n % 2 == 0:
return False
return True
if __name__ == '__main__':
userValues = GetUserValues()
if IsListEven(userValues):
print("all even")
elif IsListOdd(userValues):
print("all odd")
else:
print("not even or odd")

Hi Lily
The formatting was destroyed when you copied pasted code onto the brainly question box.
When posting code, it's better to copy the code into a text editor(such as notepad), save it as a text file and upload this through the clip icon on the bottom right of the brainly toolbar (at the bottom)
Anyway, I copied your code and properly formatted it and it works fine
Since I cannot see the formatting, I am assuming that your return True statements are improperly indented. These statements should go with the for loop, not the if statement
Here is the wrong way to define
def IsListEven(myList):
for n in myList:
if n % 2 == 1:
return False
return True #this belongs to the if statement
If you write your code as follows, the return True goes with the if statement. That means it will return from the function as soon as it finds an even number without checking the rest of the list. For example if the list was [2, 4, 6, 8, 1], the function will return True on the first element in the list without going through all the elements
The correct way is:
def IsListEven(myList):
for n in myList:
if n % 2 == 1:
return False
return True # now belongs to the for loop

Explanation:
what is the problem ? does it not compile or run at all ? it do you get something unexpected ?
did you specify your whole program or just a part ?
based on what I see I would assume it does not compile and produce, so your cannot even start it.
and that should be because the way you defined printAnswer.
you did not specify types for the parameters, and because there is also no call of printAnswer, the compiler does not have any clue about the types that way either.
for userOutput this was different, because the return statements of all the functions (add, subtract, ...) provide the type information.
also, there is no end for the function printAnswer.
the compiler simply goes on after the print statement, assuming that the following still belongs to printAnswer and finds an if-starement checking a variable __name__, which might be unknown to the compiler (if there are no other definitions included at least in the background). and then a call of main.
and then finally printAnswer is finished.
further observations :
the print statements in userOutput clearly want to use strings, but you did not include any ' signs.
I think you meant them to look like
print(firstNumber, ' + ', secondNumber, ' == ', total)
our did you mean it as a user guideline for selecting or rather specifying an operation on the 2 numbers entered earlier ?
then it would be like
print('firstNumber + secondNumber == total')
then you never call printAnswer or userOutput anywhere. you don't ask for the user input anywhere to select the desired operation. and you don't check that input anywhere to define what operation to perform.
so, the main program will ask for the 2 numbers and then simply end.

You need to contact a client on the phone. You have estimated that you have a 70% chance of contacting the client on the first call. If you don't, you estimate that you have a 20% chance of contacting the client on a subsequent call in the next hour. Which of the following is true?
a. The probability that you will need at most two calls to contact the client is 0.90.
b. The probability that you will fail on call 1 but will succeed on call 2 is 0.06.
c. The probability that you will fail on call 1 but will succeed on call 2 is 0.50.
d. The probability that you will need at most two calls to contact the client is 0.80.
From the information provided, the correct answer is Option B - " The probability that you will fail on call 1 but will succeed on call 2 is 0.06." See further explanation below.
What is probability?Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
Hence,
P(E) = Number of favorable outcomes/Total Number of outcomes.
Step I
From the information provided, the probability of failing to contact the client on the first call can be computed as:
30% = 0.3
[Rationale is based on estimation. If there is an estimated 70% chance of success, then the chance of failure is 30% which is 0.3]
Step II
The probability of contacting the client on the second call is: 0.2 or 20% [Rationle is as per the given assumption.]
If the two scenarios above hold out because they are mutually exclusive events, the probability, therefore, that you will fial on call 1 and succeed on call two becomes:
0.3 x 0.2
= 0.06
