Hi! The answer is 8 ounces of canned tomatoes and 1 cup of cooking macaroni.
This is because you want a quarter (1/4) of the servings so you only need a quarter of the ingredients and to get a quarter of something you just need to divide it by 4 so
There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.
