Multiple-choice questions each have four possible answers left parenthesis a , b , c , d right (a, b, c, d), one of which is correct. assume that you guess the answers to three such questions.
a. use the multiplication rule to find p(wwc), where c denotes a correct answer and w denotes a wrong answer.
p(wwc)=

b. beginning with wwc, 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(wwc)minus−see above
p(wcw)=
nothing
p(cww)=

c. based on the preceding results, what is the probability of getting exactly one correct answer when three guesses are made?
