A multiple-choice test has six possible answers for each question.
(a) If a student guesses at the answer, what is the probability that he or she selects the correct answer for one particular question?
(b) If the student first eliminates one of the six possible answers and guesses from the remaining possibilities, what is the probability that he or she selects the correct answer to that question?

a) The probability of getting the correct answer =  

b)  The probability of getting a correct answer after eliminating one answer is  

Step-by-step explanation:

Step 1 :      

Number of possible answers available for each question  = 6

a)

The student takes a guess at the answer, we need to obtain the probability of selecting the correct answer.

This can be obtained by dividing the favorable outcomes by the total available  outcomes =

Hence probability of getting the correct answer =  

Step 2 :

b)

The student eliminates one of the six possible answers. Hence the total possible answers available here is 6 - 1  = 5

The probability that the student guesses the correct answer from the available 5 answers is

The probability of selecting a correct answer after eliminating one answer is  

Step 3 :

Answer :

a) The probability that student selects  correct answer =  

b)  The probability that student selects correct answer after eliminating one answer is

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
