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?

1.) This probability can be modeled by \[14 nCr 10 (.5)^{10}(.5)^{4}\] which equals roughly 6.11%. 2.) This probability can be modeled by 1/6 * 1/2 * 1/2* 1/2 * 1/2 which equals 1/96 or 1.04% Hope that helps
