Question

Leanna guesses on four multiple choice test questions in a row. if each question has 3 possible answers, what is the probability that leanna will guess the answer to the 4th question correctly?

Answer 1

The sole relevant fact is that there are three viable responses, making the likelihood of selecting the correct response 1/3.

The correct option is C.

What is Probability?

Probability is the ability to happen. The subject of this area of mathematics is the occurrence of random events. From 0 to 1 is used to express the value. To forecast how likely occurrences are to occur, probability has been introduced in mathematics. The degree to which something is likely to happen is essentially the definition of probability. This is the fundamental theory of probability, which is also applied to the probability distribution, and from which you will discover the likelihood of results for a random experiment. We must first determine the total number of outcomes in order to calculate the probability that a single event will occur.

Briefing:

It has no bearing on how question 4 is guessed whether there are questions before (or after) it. The likelihood of getting a head on the fourth flip is the same as the probabilities of the first three flips, therefore this is quite similar to asking how likely it is to get a head on the first four flips of a coin.

The sole relevant fact is that there are three viable responses, making the likelihood of selecting the correct response 1/3.
