And or Rules of probability

[huyanhle]

Can anyone help me how to solve this question please!

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:

(i) She chooses soup, fish and lemon tart (Answer = 1/36)
(ii) she chooses all three courses (Answer = 1/4)
(iii) she chooses only two courses (Answer = 1/2)
(iv) she has only the main course. (Answer = 1/4)
