What is the probability of guessing the correct?

For every question, there are two outcomes: Either you answer correctly or you don’t. If you pick a random answer, the probability of guessing the right answer is one out of four, 1/4, or 0.25. Consequently, the probability of guessing wrong is a lot higher at 3/4 or 0.75.

What is the probability of correcting at least four questions among 5 True or false questions?

We want the probability that we get at least 4 answers correct since we need 4 correct answers at a minimum to achieve a passing grade. Thus the probability of passing is 0.34375. There are 32 possible ways 5 true/false questions can be answered, 2 ^ 5 = 32.

What is the probability of making 3 correct guesses in 5?

0.3125
What is the probability of making 3 correct guesses in 5 True – False answer type questions? 0.3125.

What is the probability of guessing correctly on four true false questions in a row?

Assuming each of these 16 sequences is equally likely to occur (as would result from random guessing), the probability that all four questions are answered correctly is 1/16.

What is the probability of guessing the first 5 questions correctly?

Probability of guessing all 5 correctly: 1/3125=0.032\% Probability of guessing the first question correctly: 1/5 For that 1/5 of the time when the first question has been guessed correctly, the second question could be guessed correctly 1/5 of the time. So the first two questions could be guessed correctly 1/5xx1/5= (1/5)^2 of the time.

What is the probability of the first two right next three wrong?

And it is the Muliplication Rule. To make typing simpler, I will take k = 2, n = 5. Write C for correct, N for not correct. By the Multiplication Rule, the probability of C C N N N (first two right, next three wrong) is ( 1 / 3) 2 ( 2 / 3) 3.

How many possible answers are there in a multiple choice test?

A multiple choice test has 5 questions each with 5 possible answers. What is the probability of guessing all the questions correctly? Probability of guessing all 5 correctly: 1 3125 = 0.032\% Probability of guessing the first question correctly: 1 5

What is the chance of guessing all 5 correctly?

The chance of guessing one answer on its own is 1/3. 45/118 is slightly more than 1/3 which means that guessing all 5 correctly is more probable than guessing only one correctly.
