A shelf holds 4 boxes of spaghetti noodles,
1 box of tortellini noodles, 1 box
of macaroni noodles, and 12 boxes of
egg noodles. Without looking you grab
one box of noodles. What's the
probability that it's tortellini noodles?

1 in 14   or   1/14

this is the formula I used to calculate:

Probability = Favorable cases / Possible cases

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
