Question

Each question of a 5 question multiple choice exam has 4 possible answers

Suppose a student picks an answer at random for each question.
Find the probability the student select the correct answer on all of the questions

Answer 1

Explanation:

the test has 5 questions

Each question has 4 answers

Test value = 1/4 * 1/4 * 1/4 * 1/4 * 1/4

Test value = 1/1024

Test value = .0009766

The probability is very low. Better to study, wouldn't you think.
