Question

emily has a basket of cookies. there are 30 chocolate chip, 30 sugar, and 15 peanut butter cookies. what is the probability of a randomly selecting a cookie that is not peanut butter?

Explanation:

Step1: Calculate total number of cookies

Total = \(30 + 30+15=75\)

Step2: Calculate number of non - peanut butter cookies

Non - peanut butter = \(30 + 30 = 60\)

Step3: Calculate probability

Probability \(P=\frac{\text{Non - peanut butter}}{\text{Total}}=\frac{60}{75}=\frac{4}{5}=0.8 = 80\%\)

Answer:

\(80\%\)
