Roll a number cube. If you get a 1 pick the first answer, if you get a 2 then pick the second answer, and so on. If you get a 6, then roll again.number die. You could do the same with a random number generator or the decimal expansion of any irrational number. If the digit is 1 or 2 then pick the first answer, if the digit is 3 or 4 then pick the second answer, etc.

There are several solutions....what are the choices you have? Guessing one of them is (1,-4) or possibly (-1,-5). --Algebra 2 Teacher

"which" implies there are choices. So what are the choices?

It is 1/5.

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.

1/4

Without knowing what the choices are, we'd only be guessing.

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.

You did not give us the list of the following objects- and we are lousy at guessing. Please repost your question, but tell us what the possible choices are.

I'm guessing you could, but that depends if you think you can make good choices, if you know what I mean

question with options, you will lose of the credit for that question. Just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing. With five choices, your chance of getting the question wrong is 80% when guessing, and every wrong answer costs you 1/4 of a point. In this case, leave it blank with no penalty. Guessing becomes a much better gamble if you can eliminate even one obviously incorrect response. If you can narrow the choices down to three possibilities by eliminating obvious wrong answers

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.

A shell mesh is a series of Finite elements that use shell representation of a surface to predict the behavior of the part. Beam or solid elements would be the other choices. Shells are generally used to simulate most auto body structures.
