A. The answer is 3125
@Gabe is right for 2022!
Oh, no. Sorry. for the capitalization error.
Yeah he is right for 2022
To find the probability of answering all the questions correctly, we need to determine the probability of correctly answering each question and then multiply these probabilities together.
In this case, each question has 5 possible answers, and we are aiming to select the correct answer each time. Therefore, the probability of correctly answering a question is 1 out of 5, or 1/5.
Since there are 5 questions in total, we need to multiply the individual probabilities together:
P(correctly answering all questions) = (1/5) * (1/5) * (1/5) * (1/5) * (1/5)
Simplifying this expression yields:
P(correctly answering all questions) = 1/5^5 = 1/3125
Therefore, the correct answer is A. 1/3,125.
