There are 70 questions. The probability of getting any one of the questions right is 0.2. That's because there are five answers only one of which is correct.

If there are 5 questions and you want to pick the right one the probability is 1/5. If you don't know how to find that, let your calculator walk you to the answer.

1
÷
5
=
And it will tell you that it is 0.2.

So if you blindly (not brainly) fill in the multiple choice answer sheet, the number you will get right is
(P(0.2) * The total number of questions or
0.2 * 70 = 14
Just pure dumb luck will give you 14 correct answers.
