Use a suitable probability calculation to decide what contestant should do ( assume that they are aiming for cash rather than the carrots)

Ok, for this question I dont really understand, just know that P(carrot) = 1/3. I dont even have a clue how to do it and what kind of probability calculation to use. Can somebody give me the structure to do this question please?.

Any help would be appreciated! . Thanks for your time
