15%? (My math sucks - I probably got that wrong).
1/2
As of 2010 there is 18 multiple question. You have to get 15 answers correctly
A multiple of 6 because you can get a 6 and 6, a 1 and 5, a 2 and 4, and a 3 and 3. The only factors you can get are 2, 3, and 6.
A common multiple
Any multiple of 30 is also a multiple of 15.
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.
It is 0.25
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.
You have a 4 percent chance of guessing both answers correctly assuming there is only one correct answer to each question and that you may only answer once per question.
i believe it would be a (1/4)^5 chance. if youre going that route, good luck
7 to 1
If I understand the question correctly, the answer is 3/10.
Not sure what a mulitple choice qustion is but if it is anything like a multiple choice question, it is 1/5 or 20%. I strongly advise you to get a dictionary, learn to spell or use a spell checker.
7:1
That depends a lot on the specific circumstances, of how you guess. For instance, if a test has true/false questions, the probability is 1/2; if it is a multiple-choice question with 4 options, the probability is 1/4; if there are 6 options, the probability is 1/6, etc.; if you have to calculate a number (and it is NOT a multiple choice question), the probability is rather low, indeed.
The probability will depend on how much you know and the extent of guessing.
