Components of type A have heights that are independently distributed as a normal distribution with a mean 190 and a standard deviation of 10. Components of type B have heights that are independently distributed as a normal distribution with a mean 150 and a standard deviation of 8.

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.
