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
What are the odds of getting 100 percent on a 10 question multiple choice test where each question has 2 possible answers?
The odds of getting 100 percent on a 10 question multiple choice test with 2 possible answers for each question can be calculated using the probability formula. Since there are 2 options for each question, the probability of getting a question right by guessing is 1/2 or 0.5. To calculate the probability of getting all 10 questions correct by guessing, you would multiply the probability of getting each question right (0.5) by itself 10 times, resulting in a probability of (0.5)^10, which is approximately 0.0009765625 or 0.09765625%.
Under Binomial distribution a standard test consists of multiple choice questions with 5 possible choices. How do you ensure that a student who randomly guesses will obtain an expected score of 0?
In a Binomial distribution, if a student randomly guesses on multiple-choice questions with 5 possible choices, the probability of selecting the correct answer is ( p = \frac{1}{5} ) and the probability of selecting an incorrect answer is ( q = 1 - p = \frac{4}{5} ). The expected score for a student guessing on ( n ) questions is calculated as ( E(X) = n \cdot p ). To ensure that a student who randomly guesses has an expected score of 0, the number of questions ( n ) must be set to 0, or alternatively, the scoring system must be adjusted so that the expected value of scoring remains zero, such as by introducing penalties for incorrect answers.
In a randomly generated list of numbers from 0 to 4 the chance that each number can occur is .?
In a randomly generated list of numbers from 0 to 4, each number (0, 1, 2, 3, and 4) has an equal chance of occurring. Since there are 5 possible outcomes, the probability of each number appearing is 1 out of 5, or 20%. Therefore, the chance for each number is 0.2.
If a box contains one red ball and one blue ball and two people touch one ball randomly with a one in two chance of picking either what is the chance of the blue ball being picked twice?
One in four. The possibilities are; Red Red Blue Red Red Blue Blue Blue That means the number of ways an event can occur is one, while the number of possible outcomes is four. The definition of probability is the number of ways the event can occur over the number of possible outcomes, hence 1/4
You sit down to take a true-or-false test with 6 questions If you randomly guess on all questions how many possible outcomes are there for the 6-question test?
The number of possible outcomes would be 2^6 = 64, since each of the six questions have two possible outcomes.
When did Lenny Aisha die where?
Sorry, but that question is unanswerable. The brain tree randomly generates outcomes. There fore there is no set answer.

What is the probability of randomly choosing a vowel from the letters a b c d e?
There are 5 letters in the set {a, b, c, d, e}, and 2 of these letters are vowels (a, e). Therefore, the probability of randomly choosing a vowel from this set is the number of favorable outcomes (2 vowels) divided by the total number of possible outcomes (5 letters), which equals 2/5 or 0.4.

Can you answer questions that your friends have answered about you in 21 questions?
You sometimes can, if they come up randomly, but there is no way to select them specifically to answer.
