Answer 6

Answer 7

suppose there is 1 main course, and 3 beverages.

If get to choose 1 main course and a drink, how many combination of meal can I possible get?

Answer 8

3?

Answer 9

why not 1 + 3 = 4?

Answer 10

Umm... idk, I can't explain it myself, sorry :(

Answer 11

it's not 4 because you don't get to take everything in one meal. You're limited to choose a single kind in each.

Answer 12

so you could have
main course + first beverage, or
main course + second beverage, or
main course + third beverage.

that is precisely 1 * 3 = 3

Hmm... makes sense. I get it a bit more now, thanks :)
