Sir, can you answer my question? Students take the semester exam for course A. In the exam, they are given 20 multiple choice questions, with 5 answer choices. Of the 5 choices available, there is only 1 correct answer. Based on this information, calculate: a) What is the probability that students can answer 2 questions correctly b) What is the probability that students can answer 10 questions correctly.
Hei, you can use binomial distribution (see my video), and choose a p = 0.2 (if no more information than then problem description here), so will be easy to calculate probabilities for these two questions.

b) What is the probability that students can answer 10 questions correctly.
a) b(2,20,1/5) = 0,1369
b) b(10,20,1/5) = 0,002

Thank u sir,im done 🙏
