Final answer:
The probability of getting no correct answers in a seven multiple choice test with four possible options for each question is 0.027.
Step-by-step explanation:
To find the probability of no correct answers in a seven multiple choice test questions with four possible answers each, we need to calculate the probability of guessing all questions incorrectly.
The probability of guessing one question incorrectly is 3/4, since there are three incorrect answers out of four possible choices.
Since each question is independent, we can multiply the probabilities together:
Probability of no correct answers = (3/4)^7 = 0.027
