Reformulated, the problem's question is


<pre>
    What is the probability that her answer for the first question is wrong,
    while the answer to the second question is correct ?
</pre>


The probability that the answer to the first question is wrong is  &nbsp;&nbsp;{{{3/4}}}.


The probability that the answer to the second question is correct is  &nbsp;&nbsp;{{{1/4}}}.


THEREFORE, &nbsp;&nbsp;the final probability under the problem's question is  &nbsp;&nbsp;P = {{{(3/4)*(1/4)}}} = {{{3/16}}}.    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>
</pre>

Solved.


---------------


Notice that in this problem, &nbsp;the total number of multiply choice questions &nbsp;(5, &nbsp;as given) &nbsp;does not matter,


as well as what kind the questions are after the second question.



Only the nature of the first two questions does matter.
