If a student guesses on a multiple-choice test with 4 options per question, what is the probability of guessing one question correctly? (2023)
Steps
Concepts
Step 1: Understand that there are 4 options for each question.
Step 2: Identify that only 1 of those options is the correct answer.
Step 3: To find the probability of guessing correctly, use the formula: Probability = (Number of correct options) / (Total number of options).
Step 4: Plug in the numbers: Probability = 1 (correct answer) / 4 (total options).
Step 5: Simplify the fraction to get the final probability: 1/4.
Probability
– The likelihood of an event occurring, calculated as the number of favorable outcomes divided by the total number of possible outcomes.
Multiple-choice format
– A test format where each question has several options, and only one is correct.
