You're having dinner at a restaurant that serves 555 kinds of pasta (spaghetti, bow ties, fettuccine, ravioli, and macaroni) in 444 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?

Total combinations are the number of pastas x the number of sauces:

5 x 4 = 20 different choices.

For it not to be tomato’s spaghetti you would have 19 choices it could be ( 20 total - 1(tomato spaghetti) = 19

The probability of being something other than tomato spaghetti would be 19/20

The answer is 19/20

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
