Question

Richard has just been given a 8-question multiple-choice quiz in his history class. Each question has five answers, of which only one is correct. Since Richard has not attended class recently, he doesn't know any of the answers. Assuming that Richard guesses on all eight questions, find the indicated probabilities. (Round your answers to three decimal places.)

Answer 1

Answer:

0.256 * 10⁻⁵

Step-by-step explanation:

Probability of picking any answer out of 5 given options = 1/5

Total probability for 8 questions = (1/5)⁸ = 0.00000256

= 0.256 * 10⁻⁵
