Answer:
Number of ways chosen cookies = 8 ways
Step-by-step explanation:
Given;
Total number of chocolate chip cookies = 16
Total number of oatmeal raisin cookies = 12
Total number of cookies choose = 3
At least 1 chocolate cookie
Find:
Number of ways chosen cookies
Computation;
Number of total ways = 2³
Number of total ways = 8
If at least on cookie is chocolate cookie,
Number of ways chosen cookies = Number of total ways - 1
Number of ways chosen cookies = 9 - 1
Number of ways chosen cookies = 8 ways
