If a student guesses on a multiple-choice test with 4 options, what is the probability of guessing correctly? (2022)
Steps
Concepts
Step 1: Understand that there are 4 options to choose from on the test.
Step 2: Realize that only 1 of those 4 options is the correct answer.
Step 3: To find the probability of guessing correctly, use the formula: Probability = Number of favorable outcomes / Total number of outcomes.
Step 4: In this case, the number of favorable outcomes (correct answer) is 1, and the total number of outcomes (all options) is 4.
Step 5: Plug the numbers into the formula: Probability = 1 / 4.
Step 6: Simplify the fraction if needed, but 1/4 is already in its simplest form.
Probability
– The likelihood of an event occurring, calculated as the number of favorable outcomes divided by the total number of possible outcomes.
Multiple-choice questions
– A type of assessment where students select the correct answer from a set of options.
