If you did NOT read before taking a quiz.... Probability question

[From: ] [author: ] [Date: 12-04-21] [Hit: ]
A) What is the probability of getting all 5 questions correct by guessing if each question has 3 answer choices (a,b, and c).B) What is the probability of getting all wrong?B) P(wrong) = 2/3,P(all five are wrong) = (2/3)^5 = 32/243-Id say your chance for A is 1 in 15 for B about the same maybe double(1 in 30) because you didnt read up.......
If you did not read before taking a quiz, you're guessing the answers.

A) What is the probability of getting all 5 questions correct by guessing if each question has 3 answer choices (a,b, and c).

B) What is the probability of getting all wrong?

P(correct choice) = 1/3

A) P( all five correct) = (1/3)^5 = 1/243

B) P(wrong) = 2/3, P(all five are wrong) = (2/3)^5 = 32/243

I'd say your chance for A is 1 in 15 for B about the same maybe double(1 in 30) because you didn't read up.
