PROBLEM 4B : 1.0 POINTS

Suppose a student guesses the answers to both Questions 1 and 2 as described in 4A, using a different toss for each question. Are the events “gets the right answer to Question 1” and “gets the right answer to Question 2” independent?

No.

Answer 5

To get an A grade on the test, you need a total score of more than 16 points. One of the students knows the correct answer to 6 of the 20 questions. The rest she guesses at random by tossing a coin (one toss per question, as in 4B). What is the chance that she gets an A grade on the test?
