The number of chocolate chips in a single chocolate chip cookie is approximately normally distributed with a mean of 12.5 chocolate chips and a standard deviation of 2.1 chocolate chips. What is the probability that a randomly selected chocolate chip cookie contains fewer than 10 chocolate chips

Step-by-step explanation:

as only whole numbers make sense for the number of chocolate chips in a cookie, "fewer than 10" means actually "9 or fewer".

so, we need the probability (area) of the specified normal distribution curve for 9.

the probabilty is about 0.05 for a cookie to have fewer than 10 chocolate chips.
