Question

The probability that a student guesses the correct answer to a four-choice multiple-choice question is ​P(correct)=0.25. How many correct answers should a student expect to guess on a test with 52 four-choice multiple-choice​ questions?
A student should expect to guess _________ correct answers.

Answer 1

Answer:

13

Step-by-step explanation:

Expected answer to be correct is 52*0.25 = 13

Since we know that 52 is the number of questions, and 0.25 is the probability of getting a correct answer we multiply them together to get the chance of getting correct answers.
