You're having dinner at a restaurant that serves 5 kinds of pasta (spaghetti, bow ties, fettuccine, ravioli, and macaroni) in 4 different flavors (tomato sauce, cheese sauce, meat sauce, and olive oil). If you randomly pick your kind of pasta and flavor, what is the probability that you'll end up with something other than tomato spaghetti?

To answer this question you will calculate all the different possibilities.

You will multiply the total possible pastas (5) by the total number of sauce choices (4). This means there would a possible 20 combinations.

Tomato spaghetti is only 1 of those choices, so there would be 19 other possible choices. You have a 19/20 (95%) probability of getting something else.
