QuestionMultiple-choice questions each have four possible answers ( $a, b, c, d$ ), one of which is correct. Assume that you guess the answers to three such questions. a. Use the multiplication rule to find $\mathrm{P}(\mathrm{WCC})$, where C denotes a correct answer and W denotes a wrong answer. $P(W C C)=\frac{3}{64}$ (Type an exact answer.) b. Beginning with WCC, make a complete list of the different possible arrangements of two correct answers and one wrong answer, then find the probability for each entry in the list. $$\begin{array}{l} \mathrm{P}(\mathrm{WCC})-\text { see above } \\ \mathrm{P}(\mathrm{CCW})=\square \\ \mathrm{P}(\mathrm{CWC})=\square \end{array}$$ (Type exact answers.)
