What is the probability of getting a question right simple by guessing?
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.
What is the probability of a 5 not being rolled on a dice?
Probability is desired options over total options. There are 6 faces on a standard dice, so NOT rolling a 5 is 5/6.
What is the probability of rolling a number less that 3 on a number cube?
If it is fair die, then the probability is 1/3.
What is the probability that a letter picked at random is not a vowel?
The probability that a letter picked at random is not a vowel depends on the set of letters you are choosing from. In the English alphabet, there are 21 consonants and 5 vowels, so the probability of picking a consonant is 21/26 or approximately 0.808.
What is the probability for drawing a red or black card?
The probability of drawing a red or black card from a standard deck of playing cards is 1 (a certainty). This is because these are the only options available.

Does probability of chance change as options are limited?
Yes.

Probability is desired options over total options. There are 6 faces on a standard dice, so NOT rolling a 5 is 5/6.

If a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct how much credit will you lose for that part of the question?
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

What is the probability of obtaining exactly four heads in five flips of a coin given that at least three are heads?
We can simplify the question by putting it this way: what is the probability that exactly one out of two coin flips is a head? Our options are HH, HT, TH, TT. Two of these four have exactly one head. So 2/4=.5 is the answer.
Complete the series using one of the options from A to E?
There are no options from A to E. It is not possible to answer the question without any options to choose from.
What cannot be a probability 0 -49 0.001 14 percent?
Probabilities can only range from 0 to 1. All of the options range from 0 to 1 (14% is the same as 0.14) except -49, so -49 is not a probability.
What is the plant like protists?
The question is incomplete. There are no options given (for "which of the following") to answer this question.
