Question

A test has multiple choice questions with 5 choices for each answer; only one answer is correct for each question.
Suppose a student guesses the answer to each question. Assuming the guesses are independent, find the probability
that the student will guess correctly when answering two questions.
o 1/5
1/10
01/25

Answer 1

Answer:

1/25

Step-by-step explanation:

The probability of guessing the first question correct is 1/5

The probability of guessing the second question correct is 1/5

Since they are independent

P(correct, correct) = P(1st correct) * P(2nd correct)

                               = 1/5 * 1/5

                               = 1/25
