Leticia has been assigned a task for which she does not have the necessary skills or knowledge. although she knows she can't do the task, she really wants the bonus she can earn by completely the task. according to expectancy theory, leticia's will be highly motivated to complete the task.

That statement is false.
Accoring to  expectancy theory, we would most likely have higher motivation to complete a task if we believe that we have a necessary skill set to accomplish it. In Leticia's situation, i believe Leticia would be much more likely to give up and pursue another interest rather than pursuing the thing that she has a small chance of completing.
