Question

The probability that a student guesses the correct answer to a five​-choice multiple choice question is ​P(correct)=0.2. How many correct answers should a student expect to guess on a test with 60 ​five-choice multiple choice​ questions?

Answer 1

Answer:

12 correct answers

Step-by-step explanation:

It is given that :

The probability of a student guessing the correct answer for a five choice multiple choice question is $\text{P(correct)}=0.2$

Number of multiple choice questions = 60

So the number of correct answers that a student are expected to guess correctly on the test is :

$=60 \times 0.2$

= 12
