The probability will depend on how much you know and the extent of guessing.

In a multiple choice question with five possible answers what is the probability the correct answer will be found?
1/5 or 0.2
A multiple choice question has has 5 choices What is the probability of guessing it correctly?
There is 1 right answer out of 5 possible answers, so the probability of guessing it correctly is 1/5 or 20% or 0.2.
Why the probability is have a specified chance to be selected and why the non probability does not have an equal of being selected?
Probability is the number of occurrences of a specific event divided by the total number of possible events. Suppose you took a multiple choice test with 4 possible answer's A, B, C, D. Only 1 of the 4 choices is correct; so the probability of correct is 1/4 and the probability of incorrect is 3/4. Most of the time the two probabilities will not be the same.
What is the probability that the spinner stop in multiple of 3. The spinner is numbered 1 through 8?
Total number of possible stops = 8Number of successful stops = 2 (stops on 3 or on 6 are successful)Probability = 2/8 = 25%
What are the 2 conditions that determine a probability distribution?
The value of the distribution for any value of the random variable must be in the range [0, 1]. The sum (or integral) of the probability distribution function over all possible values of the random variable must be 1.
What is the probability that if you just guess on five multiple choice questions each with four possible answers you will get none of the questions correct?
.237 or about 24 %
What must you do to determine the probability of multiple independent events happening a certain way?
Divide the number of events that can happen a certain way by the number of all possible events.
What is the probability of getting exactly 7 out of 12 multiple choice questions right if a student randomly guesses one of the five possible choices for each question?
It is 0.0033
Do you divide to find the probability?
Yes, you divide the number of expected outcomes by the number of possible outcomes in order to determine probability.
A multiple choice test has 8 questions that has 3 possible answers only one is correct If Judy who forgot to study for the test guesses on all questions what is the probability that she gets 3 right?
The probability that she gets exactly 3 right is 8C3*(1/3)3*(2/3)5 = 0.2731 approx.
A diagram used to determine the number of possible outcomes in a probability situation?
a sample .... i think
What does theoretical probability mean in math terms?
Sometimes it is possible to define a model for a trial or experiment and then use mathematical or scientific rules to determine the probability of the possible outcomes. Such a procedure gives theoretical probabilities.
When two balanced dice are rolledthere are 36 possible outcomes. Find the probability that the sum is a multiple of 3 or greater than 4?
The probability is 0.88... recurring.
In a multiple choice question with five possible answers what is the probability the correct answer will be found?
1/5 or 0.2
There are five questions on a quiz with four possible answers what is the probability you get 100 percent?
Probability of each question correct is 1/4 or 0.25. Since there are 5 questions, raise 0.25 to the 5th power or (0.25)5. So, probability all correct is 0.0009765.
When rolling a sixsided die a possible event is rolling a sum which is a multiple of 5 What is the probability of this event?
The probability of rolling a multiple of five on a standard die is 1 in 6, or about 0.1667.The probability of rolling a 10, 15, or higher is zero, because the question implied only one die.
Is it possible for two separate groups to conduct the same experiment to determine an experimental probability and get different results?
Yes
