A student guesses blindly on a 20 question true/false test.    

a) Using the binomial probability formula, find probability the student gets exactly 3 out 20 correct.    

b) Using the binomial probability formula, find probability the student gets 3 or less questions correct.    

c) Using a calculator or table of values, find probability the student gets at least a 60% score on the test.

Using the Binomial Distribution Assume that two students must take a ten question, True or False quiz. Student 1 has not studied at all and guesses randomly on each question. Student 2 has studied hard and has a 95% chance of answering any particular question correctly. For each student, calculate the probability of passing (getting 7 or more correct answers) and the probability of “acing” (getting 9 or 10 correct answers) the quiz. What do your calculated probabilities say about...
