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

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
