Question

Bobby wonders if he randomly guesses on four true-false questions, how would he do on the assessment? He creates the simulation below. He states that if the coin lands on heads, the answer will be correct, and if the coin lands on tails, the answer will be incorrect

Answer 1

Given the chances of getting heads, or getting the answer correct is equivalent to 1/2 or 0.5,
He has a 1/8 chance of answering all the questions correctly.
$\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \\ = \frac{1}{8}$
