Abiology quiz consists of twelve multiple-choice questions. eight must be answered correctly to receive a passing grade. if each question has five possible answers, of which only one is correct, what is the probability that a student who guesses at random on each question will pass the examination? (round your answer to four decimal places.)

There is a 0.058% probability that this student will pass the examination.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either it is correct, or it is wrong. This means that we can solve this problem using the binomial probability distribution.

Binomial probability distribution:

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

In this problem

There are 12 questions, so .

The student guesses each question. There are five possible answers, only one which is correct, so .

What is the probability that a student who guesses at random on each question will pass the examination?

This is

So

There is a 0.058% probability that this student will pass the examination.

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
