Find the probability the student selects the correct answer on all of the questions.

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.

Answer 1

Dazzmine

Well the chance of selecting the right answer on first is (1/4) = 0.25 as there are 4 possible answers

So if there were 3 questions, the probability of all correct = 0.25 x 0.25 x 0.25

Try and extend this to your problem - 5 questions not 3
