How does the probability improve of choosing the one correct answer as incorrect answers are eliminated one at a time from 5 multiple choice question such as those found on the SAT?

Probability of hitting the bull's-eye on the next random shot after eliminating . . .
- no answer . . . . . 20%
- 1 answer . . . . . . 25%
- 2 answers . . . . . 331/3%
- 3 answers . . . . . 50%
- 4 answers . . . . . 100%
- 5 answers . . . . . zero
Probability of choosing the one correct answer increases significantly from
these figures if you actually know something about the subject.

If A test has 5 multiple questions each with 5 answers what is the probability of getting 2 incorrect?
4/5 * 4/5 * 4/5 * 4/5 * 4/5= 1024/ 3125, or 37%

4/25
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 are the odds against correctly guessing the answer to multiple choice question with 7 posssible answers?
6 to 1. (That is, 6 incorrect to 1 correct.) This is equaivalent to a probability of 1/7 or a 14% chance of guessing the correct answer.

What is the probability a multiple of 5 on a fair die?
It is 1/6.
What is the probability of that you roll a multiple of 3 or 5 on a number cube?
The probability that you roll a multiple of 3 (3 and 6) in a fair die is: P(3 or 6) = 2/6=1/3 = 0.333... ≈ 33.3%.The probability that you roll a multiple of 5 (5) is: P(5) = 1/6.The probability that you roll a multiple of 3 or 5 is: P(3 or 6 or 5) = 2/6 + 1/6 = 1/2 = 0.50 = 50%
When two dice are rolled find the probability that the sum is a multiple of 3 or greater than 4?
The probability is 35/36.
Are choosing a multiple of 5 and choosing a number less than 5 mutually exclusive?
Not if you include negative numbers.
