Using the Fundamental Counting Theorem, it is found that she can choose 180 different meals.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

In this problem:
- For the meat, there are 3 outcomes, hence
.
- For the two vegetables, 2 are taken from a set of 6, hence, applying the combination formula,
.
- For the dessert, there are 4 outcomes, hence
.
Then:

She can choose 180 different meals.
