Multiple-choice questions each have five possible answers (a, b, c, d, e), one of which is correct. Assume that you quess the answers to three such questions. a. Use the multiplication rule to find P(WCW), where C denotes a correct answer and W denotes a wrong answer. P(WCW) =(Type an exact answer.) b. Beginning with WCW, make a complete list of the different possible arrangements of one correct answer and two wrong answers, then find the probability for each entry in the list. P(WCW) - see above P(CWW) = P(WWC) = (Type exact answers.) c. Based on the preceding results, what is the probability of getting exactly one correct answer when three guesses are made? (Type an exact answer.)

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
