Maths Probability question.?
Madison has a choice of two entrees (soup or salad), three main courses (fish, chicken or steak) and three desserts (ice-cream, lemon tart or cheese).
Suppose Madison has the choice to omit the entree and/or the dessert course altogether. Find the probability that:she chooses soup, fish and lemon tartshe chooses all three coursesshe chooses only two coursesshe has only the main course.
could you show how you got these answers?

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.
