Answer:
A simulation of a statistical process is any other experiment in which the probabilities are the same as in the simulated process.
For example, the probability in where a student chooses salad is a 33%, so you can simulate this by throwing a dice, where each number of the dice has an even 1/6 probability of showing up, so for example, if you choose a random student, you can throw a dice, if the results are 1 or 2 (the probability of this is 1/6 + 1/6 = 1/3 = 0.33 or 33% in percent form), the student will choose salad, if the results are 3, 4, 5 or 6, the student will choose grilled chicken.
In this case, in 33% of the throws, the student will have a 1 or 2 (chose a salad) and in the other 66% the student will have the other numbers, so he will choose a grilled chicken.
