Answer:
Carol:$25 Linda:$15
Step-by-step explanation:
Clarissa is not correct. If she were to choose one from the stack at random, it means that she has a 25%, or a 1/4 chance to pick the oatmeal, just like the other breakfast items.
If there were to be more oatmeals than any of the other items, it will heighten the chance of her getting oatmeal which would be the only way to make her statement correct.
It would be 220 because 20 students in all, 20×20 is the 400 students. so if you just multiplied the 9 and 11 by 20, it would match up with 400 students and you would have 220 girls. (This is not how most people work this out, but I hope it helped).
