7 to 1
7:1
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.
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.
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.
