    The grammar in your writing leaves a lot of room for improvement.

    However, if we have two choices for entrees, three for mains and three for dessert, then the total combinations of choices is:

    2 x 3 x 3 = 18...if she has one of each course.

    The combination of soup --> fish --> lemon tart is one of these hence, probability 1/18

    If she omits the entree, only having a main and dessert, then we have 3 x 3 = 9 combinations

    i.e. 1/9 of choosing fish --> lemon tart

    If she omits the dessert, having only the entree and main, then we have 2 x 3 = 6 combinations

    i.e. 1/6 of choosing soup --> fish

    Only choosing a main involves three choices, so 1/3 of choosing fish

    So where is the question then?

    That isn't a question. Do you not know what constitutes a question? You need to learn that before anything else.
