What is the probability of advancing to the seventh round if the contestant randomly guesses the answer to each question? Write your answer as a fraction in simplest form.

Answer:
(1)/(729)

Explanation:

Given: The number of choices in in each question =3

Therefore, the probability of guessing the right answer is given by :-


\text{P(guessing the right answer)}=(1)/(3)

Since, the probability of advancing to the seventh round is product of probability of answering correctly in all the preceding rounds i.e in previous 6 rounds.

Therefore, the probability of advancing to the seventh round if the contestant randomly guesses the answer to each question is given by :-


\text{P(Advancing seventh round )}=((1)/(3))^6=(1^6)/(36)=(1)/(729)
