The volume of a soda can has a mean of 12 and standard deviation of 0.11 what percentage of cans have between 11.9 and 12.15 soda

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
