Question 30

E is a boolean variable. Consider the following sequence of expressions:
python
not E
not not E
not not not E
not not not not E
.
.
.
This pattern keeps repeating for a thousand lines. If line number 500 evaluates to False, what is the value of E?
Hint: Two negatives make a positive.
  • True
  • False
  • Cannot be determined
Status: Yes, the answer is correct. Score: Score: 2
Feedback: This pattern evaluates True and False for the alternate line because one not operator is added in expression each time. So, if line number 500 evaluates to False that means the even-number line evaluates False and the odd-number line evaluates True. This means the line number 1 which is not E will be evaluated as True. So, the value of E is False. Hence, option (b) is correct.
Accepted Answers:
False
