10-22.

There are $18$ chocolate chip cookies, $12$ oatmeal cookies, and $10$ raisin cookies in a cookie jar. If Miguel takes a cookie from the jar without looking, what is the probability that he does not get a chocolate chip cookie? Show your work to support your answer.

Take the number of cookies that are not chocolate chip out of the total number of cookies in the jar.

Cookies that are not chocolate chips are the oatmeal and raisin cookies in this case.

$\frac{22}{40} = \frac{11}{20}$
or $55\%$
