What is the probability of answering a multiple choice question correctly If you know that one of the answer if definitely wrong but you have to guess between the 3 remaining answers?
1/3. Indeed, there were four answers you had to choose from. If one is eliminated as you know it is definitely wrong, then you are left with three possible answers, one of which is correct. Thus you have 1 correct answer out of three possible, and the probability to randomly pick the correct one is 1 out of 3, or 1/3 or 33.333 %

Things and numbers don't have probabilities. Situations and events that can happen have probabilities.
What is the probability of rolling a number that is a multiple of 3 on a die?
There are two multiples of three on a die and there are six possible outcomes. So, the probability is 2/6 = 1/3 = 0.3333 or 33.33%
A jar contains three colored marbles 10 red 15 green and 25 blue If you were to choose without looking what is the probability of selecting a green marble?
It is 15/50 = 0.3
What is the probability of rolling a five on one die of three of three times in a row?
Since there are 6 sides to the die, the probability of rolling a 5 on one roll is 1/6. Since each roll is an independent event the probability of the multiple results is the product of the probability of each result. So 2 consecutive 5's would occur with a probability of (1/6)(1/6) = 1/36
