There are n! = 1*2*3*...*n possible orders and out of these, only one is correct. So the probability is 1/n!

A student takes a 10 question multiple choice exam and guesses on each question Each question has five choices What is the probability of getting at least 6 correct out of the ten question?

To find the probability of getting at least 6 correct answers on a 10-question multiple-choice exam where each question has 5 choices (with only one correct answer), we can model this situation using the binomial probability formula. The probability of guessing correctly on each question is ( p = \frac{1}{5} ) and incorrectly is ( q = \frac{4}{5} ). We need to calculate the sum of probabilities for getting exactly 6, 7, 8, 9, and 10 correct answers. Using the binomial formula, the probability ( P(X = k) ) for each ( k ) can be computed, and then summed to find ( P(X \geq 6) ). The resulting probability is approximately 0.0163, or 1.63%.

How do you find the probability of a point landing inside a circle?

To find the probability of a point landing inside a circle, you can use the ratio of the area of the circle to the area of the larger enclosing shape (often a square) within which the point is randomly distributed. First, calculate the area of the circle using the formula (A = \pi r^2), where (r) is the radius. Then, calculate the area of the larger shape, and the probability is given by the formula: (P = \frac{\text{Area of Circle}}{\text{Area of Enclosing Shape}}). This ratio will yield the probability of a randomly selected point falling inside the circle.


If you were to flip a coin 6 times what is the probability of you getting at least four heads?

To calculate the probability of getting at least four heads when flipping a coin six times, we can use the binomial probability formula. The total number of outcomes for six flips is (2^6 = 64). The probabilities for getting exactly four, five, and six heads can be calculated using the binomial formula, and their sum gives the total probability of getting at least four heads. This results in a probability of approximately 0.65625, or 65.625%.

How do you calculate probability?

Probability refers to the likelihood of an event occurring. As such, calculating the same involves dividing the chances of an event occurring by the probable number of times that it can occur.Probability is a measure of the likelihood of an event. There are different ways to calculate probability it all depend on what probability you are trying to calculate. The general formula to calculate a probability is to divide the number of event you are trying to calculate the probability for by the total number of out comes.Think of a dice the probability of rolling a 1 is equal to 1 (there is one way we can roll a one) divide by 6 ( the total number of possible out comes, i.e. 1/6.The question is too broad. Please re-ask the question with more specifics.In general, you divide the number of anticipated outcomes by the number of possible outcomes. For instance, the probability of drawing an ace in a standard deck is 4 in 52, or 1 in 13, or 0.0769


What is the formula for Default Risk Premium?

premium=(1-Recovery Rate)*(probability of default) so if the premium is 15% and the recovery rate is 30%, then you can calculate the likelihood or probability of default. It would be (.15)=(1-.30)*probability Rearranging terms you get: probability=.21428 The Recovery Rate is the percentage of your original asset you'd recover under the default circumstance.
