Provide an appropriate response.Suppose a student is taking a 5-response multiple choice exam; that is, the choices are A, B, C, D, and E, with only one of the responses correct. Describe the complement method for determining the probability of getting at least one of the questions correct on the 15-question exam. Why would the complement method be the method of choice for this problem?
What will be an ideal response?
P(at least one correct) = 1 - P(none are correct). The alternative to the complement method is to find P(1), P(2),...P(15) and take this sum. This method is too time consuming and too difficult.
