Describe simulation to solve the following problem You quest on six true -or - false questions What is the probability that you guess exactly two answers correctly?

You have a good chance on getting two questions right of six true -or - false questions. The chances are high because you have a few questions.
--------
Let N be the number of trials for the simulation, chosen in advance.
Let U be a source of pseudorandom uniform numbers on the unit interval [0,1].
We simulate guessing on one question by taking a number from U and comparing it with 0.5. If it's greater then we call it a 'success' on the question.
trial_count = 0
success_count = 0
while True :
increment trial_count
question_success_count = 0
do six times :
if U > 0.5 then increment question_success_count
if question_success_count = 2
then increment success_count
if trial_count = N then quit loop
probability = success_count / N
This stupid system discards indentation. I regret you will probably need to reconstruct that.

What is the probability that someone will answer at least one of the eight questions correctly?
The answer to this question depends on how easy or difficult the eight questions are. If, for example, the questions were based on Godel's incompleteness theorem it is very likely that nobody could answer them - ever.
On a true or false quiz with a total of four questions what is the probability of getting all four questions correct given that the answers to the first two questions are correct?
you'd have a 50% chance of getting the 3rd and 4th question correct because you said the first 2 questions are already anwsered correctly :)
What methods would you use to determine the probability of rolling a 3 or a 5 on each of the three consecutive trials with a standard die?
If you want to ask questions about the "following", then I suggest that you make sure that there is something that is following.
What is the probability of getting a zero for feelings on the Myers-Briggs test?
In order to calculate such probability, you have to know the number of questions in that particular Myers Briggs test that refer to the Thinking/Feeling dichotomy. Assuming that you will pick answers randomly, the probability will be lower when there are more questions. For 8 questions on T/F preference, there is a 12.5% probability for a score of 0 on Feeling. For 16 questions, the probability is 6.2%. For 32 questions, the probability is 3.1%. etc. If you pick your answers according to your own beliefs, it would be very difficult to assess such a probability. However there will be a approx. 30% higher chance for a man to score 0 on Feeling than for a woman.
How do you answer an experimental probability?
Experimental probability is not something that needs to be, or even can be, answered. There may be particular instances in which there are questions about experimental probability and they can only be answered in the context on which they arose.
A test consists of 15 true false questions what is the probability if the student guesses on all 15 questions?

Georgia is taking a 5 question multiple choice quiz in which each question has 4 choices She guesses on all questions What is the probability that she answers exactly 2 of the questions correctly?
64/256
A test has 6 multiple choice questions each with 4 alternatives What is the probability of guessing 5 or more questions correctly?
i believe it would be a (1/4)^5 chance. if youre going that route, good luck
If 80 percent of the questions were answered correctly and 5 questions were missed how many questions were answered correctly?
20
What percent of questions were answered correctly if you got 7 out of 24 questions wrong?
71% of the questions were answered correctly

Correctly.
What is the relationship between statistics and probability?
Probability is used to answer questions in the category of Statistics. Probability is a basic statistic that gives numeric value to the questions; Will a specific event occur? or How certain are you that it will occur. Probability of rolling a 3 on a 6-sided die is 1/6.

I can answer a call center phone simulation by sticking on the time given, listeing to the questions properly, and just give the answer to the question not my own idea.
